>I'm still amazed how bad the Twitter.com UI is.

Yes, I have been complaining about this sporadically for a while. I mean, I once tweeted that you have to do a headstand to read the tweets in chronological order [1], and even, the text will be upside down ... :) Some time later, I think they have made some changes to that, for certain cases at least, e.g. for a thread consisting of a tweet and replies to it. But in a sense that makes things even more confusing, because now you have to sometimes read things chronologically (a tweet and its replies), and sometimes in reverse (the rest)!

Jokes apart, there are multiple issues with the UI.

[1] Yes, I know there may be a technical reason for the problem, but has anyone at Twitter tried working on a solution?.
