Does anyone else see only two replies for the first tweet? It says "THREAD" but then I don't see the thread anywhere. Twitter is terrible.

Nothing very interesting but there's 3 replies I can see, you have to click on the body of the tweet to expand the replies, whereas clicking on the comments button starts your own reply.

Yeah, Twitter is terrible.

I highly recommend this extension to remove all the annoying parts of Twitter, including the unnecessary extra click when you open a tweet from elsewhere.
