@pluralistic
I'm a fan of @pluralistic and I like (many but of course not all) long threads.
When I make long threads, I feel like it's courteous to set the 2nd and subsequent toots to "unlisted" instead of public, so that people who choose not to read that one thread don't have to scroll through a bunch of CW toots.
Anyone who does read the long thread by clicking on the first toot will still see the whole thing. Others see only the first.
