Who says it's a flex? You're projecting a lot here.

The whole point is illustrating that an audience doesn't come out of nowhere and the company is now under new management. History will not repeat itself, the world has changed, what value I perceived in Twitter has now gone because my audience there is in decline post-acquisition.

My investment of time is now worthless other than what I took away from the platform in the long-term in terms of biz and friends.

Back in the day, we used to use TweetDeck columns like IRC channels in terms of hashtags, and new tweets on x from y would appear in the relevant column. If you don't know what is, imagine a group chat, but people come and go. Of an evening, I could probably rattle off a couple hundred tweets discussing and debating. Keep in mind the original character count, and a simple response could be a dozen tweets.

It's well within reasonable limits; assuming most of your karma comes from posts you've posted about 8 times a day on HN. Sounds about right for a social media platform.
