People seem to have forgotten, or not been part of, all the message boards we used to have during the late 90s and all throughout the 2000s. The ONLY thing Mastodon brings to this is federation.

Multilevel comment and reply can be confusing but can be really useful to drill down to the detail of discussion wants.
