Was it one of the only places you found a forum for something you were interested in or a fan of? Or something else entirely?
The great digg exodus
If I recall correctly I was mostly pissed with 4chan doing jack shit against the invasion of Stormfront clowns.
Back in 2006/2007 I was reading Slashdot for tech news and stuff. I started noticing that a lot of newer content was just linking to Reddit posts, so I figured I’d cut out the middleman and jumped ship to Reddit.
Minecraft servers I played on coordinated via Reddit and Mumble. Now they’ve mostly moved to Discord, which, in my opinion, really hurt the lore and meta gaming because Discord’s steam-of-consciousness format doesn’t work well compared to a forum style message board where it’s much easier to avoid shit-tier content and find good, relevant, high quality posts.
Someone asked a particular neach question about a field I work in and as usual the answers were missing the nuance of the answer the person was questioning.
