@Mastodon for every 1 "derailed conversation" I see 10 people who are offended that anybody defaces their masterpiece by replying to it.

People replying to themselves is what what I think started X's descent into hell (the endpoint of that is that you don't need to have a blog, link to the rest of the net, ...) and I think would be must better to "just say no" to that behavior by prohibiting it.

If you wanted to make things better, how about a reply browsing UI that works?
