It's hard to overstate just how incompetent Twitter is at ... everything. If this website ever gets tags, [twitter] will have the most content.
In our show today: opening a single tweet.
When you open a single tweet, you will only see three comments. A small "see more tweets" link, and "More tweets" whose relevance is exactly zero.
The you click "see more tweets" expecting to see more tweets. Oh, no. The page will reset, and you'll have to scroll past the tweet you've already seen and past the comments you've already seen, too.
Because, in Twitter's mind, that's exactly how people want to consume content.
