Then do you think that the average person's disinterest in moving to different platforms is a bad thing? How does this affect the ideal version of the web it seems like you're advocating for?
The old web was a very different place, it wasn't as centralized and there were significantly fewer people around. There were specific forums that you'd go to for specific topics. Say you were interested in West African dances - there was usually the one forum where all the West African dance nerds hung out. At most a couple of different ones. And they were very small communities. If there were issues with the admins or moderation users could and did do mass walk-outs and create a new place.
