Measured over 39 original posts from a 30-day window, last computed on October 26, 2026.
Engagement
A typical post picks up 207 interactions against 473K followers, an engagement rate of 0.044%. Measured over 39 original posts, its engagement rate beats 57% of 20,444 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 91K times each, and 0.228% of those impressions turn into an interaction. That is about 19.2% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.4 posts a day over the last 30 days, though only 37% of days saw any activity at all. Most posts go out around 14:00 UTC, and Saturday is the busiest day of the week. Of the 39 posts sampled, 79% carry an image or video and 13% link out. The account's strongest tracked post pulled 22K interactions, about 104x its own typical post.

Compared with accounts its own size
David Tsai/蔡慎坤's engagement rate beats 57% of the tracked X accounts closest to it in follower count (20,444 accounts, accounts of similar size (decile 10 of 10)). A percentile is spread evenly by construction, so 50 really is the middle of that group and 90 really is its top tenth.
On engagement per impression rather than per follower it beats 17% of the same group. When those two numbers disagree, the gap is about how far its posts travel rather than how people react to them.
Where this sits in the catalog
At 0.044%, David Tsai/蔡慎坤 sits above the 25th percentile of the 204,694 accounts in this comparison. That places it in the below the median band, which runs 0.024% to 0.143%.

Posting timing
This account posts most often around 14:00 UTC, and Saturday is its busiest day of the week. The bars below are the catalog-wide pattern, with this account's own busiest slot marked. They do not show how this account performs at each hour: we keep one aggregate per account, not one per hour, so that measurement does not exist in our data.

Formats this account uses
Its own posting mix on the left, and what each of those formats does across every account we track on the right. Only formats where the effect clears our publish test appear here, so an empty row is a format we could not measure rather than one that does nothing.
| Format | This account | Catalog effect | 95% interval | Accounts behind it |
|---|---|---|---|---|
| Image or video | 79% of posts | +111% | +108% to +115% | 34K |
| Outbound link | 13% of posts | -41% | -42% to -40% | 32K |
| Typical length | - | +15% | +14% to +16% | 32K |
- 79% of this account's sampled posts carry an image or video. Across the catalog, posts with an image or video run 111% above the same accounts' other posts.
- 13% of its posts carry a link off X. Across the catalog, posts with an outbound link run 41% below the same accounts' other posts.
- Its average post runs 592 characters, which falls in the over 280 characters band. Across the catalog, posts over 280 characters run 15% above the same accounts' other posts.
These are catalog-wide differences applied to this account's own posting mix, not a measurement of how each format performs for this account specifically. We keep one median per account, not one per format per account, so the second thing is not something this data can tell you.

刚才看了看中国的网络才发现,“日本旅游业凉了“竟然冲上了百度热搜榜。原来是因为上个月里中国的赴日游客比去年同期减少了56.1%,中国许多媒体就以此为根据来炒作话题,制造一种中国游客不去日本,日本的旅游业就要凉菜的假象。但实际上,虽然中国游客的数量腰斩,但因台湾,韩国游客暴涨,日本七月份的外国游客总数不仅不减,还达到了344万人的新高。中国人不来,照样有人会来。而中国媒体为维持可怜的体面不惜公然造谣,实在是可悲可笑!

习近平上台之前,时任中国人民大学国际关系学院政治学系教授的任剑涛曾对习近平进行过一番分析评价。预测习近平上台后中国将要进入毫无生气的20年。这个预测到现在成为了事实。 任剑涛说,(有人)说习近平在浙江就非常好学,思想非常开明。所以习近平一上台后,第一,要平反六四;第二,要进行政治体制改革;第三,一脚要把某种体制给踹掉,几乎是“戈尔巴乔夫第二”。“这基本上是中国人发挥的文学想像和创作,为十八大提前进行文学消费。”任剑涛剖析,像习近平、薄熙来,王岐山出生在50年代,以及胡春华,周强,孙政才出生在60年代的人进入高层后,这些人会愈来愈缺乏人格魅力。 他断言,中国即将面对的一个基本的状况是,要进入一个毫无生气的二十年。任剑涛进一步剖析说,因为这两代人都是红卫兵、红小兵出身,而红卫兵、红小兵最大的特点就是没规则。他表示,像50年代和60年代这两代人基本上是在毛泽东无产阶级专政下,继续革命理论的教育下和熏陶下,走向高中毕业。在大学的时候,基本上是在恢复共产党的权威,没有接受到真正的现代严格的知识训练,很难有现代观念。因而他们无法把一个制度的权威和人格的权威清晰的区别开来。 任剑涛指出,习近平这些人以为自己还能够重新塑造人格魅力,声嘶力竭地讲一些不著边际的政治空头口号,他认为他的权威就塑造起来了,其实,习近平在他的同代际中的内部,号召力都已经严重不足了。

海外中文频道会越来越热闹。有网友非常肯定的说袁腾飞已经举家到了美国,之前袁腾飞想借道澳门出境就被拦下,9.15大限在即,袁腾飞是怎么出来的倒是很有意思。如果对袁腾飞这样的大V放行,困守在传媒大学的崔永元会不会突然放出来呢? 看到老梁跟大老王会合,也是颇感意外,过去十年,中文互联网公共表达空间发生了很大变化,一些曾经活跃在电视、微博和视频网站上的人物淡出了公众视野,随着海外中文自媒体兴起,给这些熟悉的身影提供了全新的舞台。当越来越多的媒体人、文化名人和公共知识分子,把海外平台当成新的表达阵地,这个趋势继续下去,海外中文频道可能很快变成一场颇为热闹的“故人重聚”。 到那时候,大家才知道是不是真有眼福了,这些人到了自由世界,当年电视上没说完的话,微博上不敢说的话,能不能敞开聊,不妨先等等再期待。

中國國防部最近又鬧了一個歷史笑話。 8月27日,中國國防部發言人張曉剛在記者會上批評日本國會議員參拜靖國神社,還把矛頭指向台灣。他宣稱,靖國神社除了供奉14名甲級戰犯之外,還供奉了「雙手沾滿台灣同胞鮮血」的安藤利吉、乃木希典等人,並藉此痛罵民進黨政府「媚日戀殖、認賊作父,令人不齒」。 問題是,乃木希典根本沒有被供奉在靖國神社。這不是什麼冷知識,而是稍微查一下資料就能知道的基本常識。 乃木希典是日清、日俄戰爭時期的日本陸軍大將,也曾在1896年至1898年間擔任台灣總督。1912年明治天皇去世後,乃木與妻子殉死。由於他不是戰死或因戰爭相關原因死亡,因此並未合祀於靖國神社。實際上祭祀乃木夫婦的,是東京赤坂的乃木神社。 也就是說,中國國防部發言人在正式記者會上,義正詞嚴地痛罵了一件根本不存在的事情。 更值得注意的是,中國方面還直接把乃木希典定性為「雙手沾滿台灣同胞鮮血的人」。乃木擔任台灣總督時,正值日本統治初期,很多施政內容的確可以討論。但歷史評價必須建立在具體史料之上。 台灣的歷史,應該由台灣人自己研究、自己評價,而不能由中國政府替台灣人決定,誰是「恩人」、誰是「劊子手」。 這次最可笑的是,中國軍方的發言人連最基本的歷史功課都懶得做,把錯誤史實堂而皇之地說出口,再以這個錯誤為基礎痛罵日本、教訓台灣。 當歷史只是政治宣傳的工具,需要反日時就拼湊幾個日本軍人的名字,需要罵台灣時就替台灣人發明一套「歷史記憶」,為了反日而反日,為了政治宣傳可以不顧史實。這種做法最後暴露出來的,只是自己的傲慢與無知。 另外,這個週三9月9日下午,印太戰略智庫將在台北圓山大飯店舉辦「台日外交國防論壇」,多位日本國會議員將專程來台,與台灣外交、國防專家面對面交流。免費入場,名額有限,歡迎大家踴躍報名,也請幫忙分享。 圖1: 乃木夫婦殉死當天早上 圖2: 乃木神社是現在日本人舉行結婚儀式的熱門地點

西藏规划了上百座水电,高山峡谷原本就是地震、滑坡、冰崩、泥石流高度活跃的脆弱地带,一旦再叠加大规模爆破、隧洞开挖、筑坝蓄水、道路施工和河道改造,任何一个环节都可能成为风险放大器。灾害发生之前,上游究竟修了什么、炸了什么、挖了什么?河道和山体有没有受到工程扰动?有没有监测到异常?预警为何没有发挥作用?相关工程的环评、施工记录和水文数据能不能全部公开? 如果官方坚持说这完全是一场自然灾害,那就更应该把卫星影像、冰川监测、水位变化、工程施工记录以及灾前灾后的完整时间线拿出来,让外界独立核验。不能一出事就把所有责任推给冰川和极端天气,却对大规模基建造成的叠加风险避而不谈。

关于毛新宇将军的笑话很多。有个老板跟他很熟,早年经常请他到南方去玩,有一次安排了小姐,玩了他给钱的时候拿出百元大钞问小姐,你知道这是谁吗?小姐说不知道,毛新宇直接告诉小姐:这是我爷爷! https://t.co/f3NMTh1XyX

「被囚五年不低头:香港大律师邹幸彤今日迎来国安案裁决(2026.08.21)」邹幸彤,1985年1月24日出生于香港,是香港大律师、人权捍卫者及前香港市民支援爱国民主运动联合会(支联会)副主席。 她曾在英国剑桥大学学习自然科学和地球物理学,并继续从事地震研究。后来,她放弃原来的学术道路,返回香港学习法律,成为大律师,长期关注中国大陆及香港的人权问题,并为因参与社会运动而遭到检控的人士提供法律协助。 2016年,邹幸彤出任支联会副主席。支联会成立于1989年,长期要求平反八九民运、追究六四镇压责任、释放中国政治犯,并连续30多年在香港举办六四烛光晚会。 《香港国安法》实施后,六四晚会遭到禁止,支联会也成为当局重点打压的对象。2021年6月4日,邹幸彤因呼吁香港市民以自己的方式悼念六四而被捕;同年9月8日,她因拒绝向国安警察提交支联会成员、财务及活动资料再次被捕。 面对当局的压力,她没有妥协。她否认支联会是所谓“外国代理人”,也拒绝配合港警对民间组织的大规模资料搜集。即使明知拒绝服从可能令自己失去自由,她仍然选择坚持自己的判断,并为此付出了长期被囚的代价。 随后,邹幸彤与支联会前主席李卓人、前副主席何俊仁及支联会,被控“煽动颠覆国家政权”。控方把支联会长期提出的“结束一党专政”等政治纲领,指控为煽动他人颠覆中国国家政权。 从2021年9月被捕至今,邹幸彤已经被持续还押近五年。法院十多次拒绝她的保释申请,案件也一再延期。面对漫长的囚禁、孤立和最高10年监禁的威胁,她始终拒绝认罪,也没有宣布退出公共事务或放弃原来的政治主张。 在法庭上,具有大律师资格的邹幸彤多次亲自为自己辩护。她坚持指出,支联会数十年来一直通过和平方式表达诉求;悼念六四、追究镇压责任、要求政治改革以及主张结束一党专政,属于言论、结社和政治表达自由。 香港时间2026年8月21日,香港高等法院将对支联会“煽动颠覆国家政权”案作出裁决。裁决前夕,邹幸彤通过其Patreon专页感谢外界一直以来的支持和祝福,并表示“公道自在人心”,不需要仰望这种从上而下的判决。她同时披露,自案件开审后,香港惩教署改变了押送方式,每次出庭均为她同时戴上手铐、脚铐、腰链和脚链,再由惩教人员以铁链牵引押送。特制手铐和腰链将她的手腕及上身固定,迫使她在从大榄女惩教所前往西九龙法院的途中持续缩肩、弯背和屈腕;加上还要携带沉重的法庭文件,手铐会深深压入手腕,留下整天无法消退的勒痕。即使承受这样的痛苦,她仍将往后的押送形容为锻炼身体耐受力的“初阶训练”。 由于邹幸彤和李卓人至今仍然拒绝认罪,如果罪名成立,两人可能面临最高10年监禁。

习近平委托李强赶赴吉隆口岸现场,说明灾情超出了常人的想像,与此同时,娱乐八卦铺天盖地而来,孙宇晨、景甜,包贝尔、红衣女子……这一切都是为了转移舆论的视线,中宣部网信办是抓住时机抛出威力更大的震撼弹!新华社消息,十四届全国人大常委会第二十四次会议28日下午闭幕。会议经表决,决定免去张又侠的中华人民共和国中央军事委员会副主席职务,免去刘振立的中华人民共和国中央军事委员会委员职务。 此次最新被宣布免职的还包括内蒙古、黑龙江、福建、江西等多省市自治区的人大代表。以及习近平的贴身秘书钟绍军中将,还有巨乾生上将。习近平终于在这个特殊时刻,把第一军委副主席,把红二代军二代最有实力的代言人逐出了政坛。

大门正在关上。从今以后,只有被允许出境的人才能出境,手拿一本护照,买张机票便想走就走的那份潇洒,或许正在成为过去。 很多变化并不是某一天突然宣布,往往是一点一点发生的,先多一道手续,再多一份证明,先限制少数人,再扩大适用范围,直到有一天回头看,才发现曾经理所当然的选择,已经变成了一种需要被批准的资格。 护照还在手里,航班依然起降,但决定一个人能不能走的,已经不再只是自己的意愿。

Reading these numbers
A typical post picks up 207 interactions against 473K followers, an engagement rate of 0.044%. Measured over 39 original posts, its engagement rate beats 57% of 20,444 tracked accounts of a similar size, which puts it in the middle of its size range rather than at either end. Posts are seen about 91K times each, and 0.228% of those impressions turn into an interaction. That is about 19.2% of the follower count, which is the gap between an audience on paper and an audience in a timeline. Posting runs at about 2.4 posts a day over the last 30 days, though only 37% of days saw any activity at all. Most posts go out around 14:00 UTC, and Saturday is the busiest day of the week. Of the 39 posts sampled, 79% carry an image or video and 13% link out. The account's strongest tracked post pulled 22K interactions, about 104x its own typical post.
- What is David Tsai/蔡慎坤's engagement rate on X?
- David Tsai/蔡慎坤 (@cskun1989) has an engagement rate of 0.044%, based on the median interactions across 39 original posts from the last 30 days against 473,256 followers. Replies, reposts and quote-posts of other people are excluded from that sample.
- Is that a good engagement rate?
- At 0.044%, David Tsai/蔡慎坤 sits above the 25th percentile of the 204,694 accounts in this comparison. Those comparison accounts are all large ones, because our scanning cadence is weighted towards big accounts, so this is a ranking among peers of similar scale rather than a ranking across X.
- Does @cskun1989 have real engagement?
- Its engagement rate beats 57% of the tracked X accounts closest to it in follower count (20,444 accounts), which puts it in the middle of its size range group. Ranking inside a size band matters because engagement rate falls as accounts grow, so a raw rate would mostly re-measure the follower count. It is a starting point for a look at follower quality, not a verdict on it.
- When does @cskun1989 post?
- Most posts go out around 14:00 UTC, and Saturday is its busiest day, at roughly 2.4 posts per day across the measured window.
