For most communities, especially some of the smaller ones, have posts that are only as recent as 2 months ago at best. I noticed that there is frequent activity on The big communities such as "chapotraphouse", "chat" and "news"... but that same frequency of activity isn't replicated on most of the other communities.
For communities like "movies and tv shows", it feels like visiting a ghost town.
Is activity for people here mostly off this site and elsewhere? Did I not get an invitation or something? It feels like, with regards to activities such as playing games or watching a movie, I see no signs of people on this site doing anything.
So why are most communities lacking in activity?
Yeah, this is definitely an interesting question. I'm always astonished at the number of comments the megathreads get. If every one of those comments was a post in a community on the site, it would "feel" more "active". I wonder how many communities active users actually subscribe to. Sometimes I'll post something, and it feels like it goes to the void, even though the community might say it has a number of subscribers.
I have no idea how someone can follow the megathread comment section. With thousands of comments, maybe hundreds of top-level comments, it seems really daunting to dive into.
The megathread really is a community of its own. In honesty, I'd never even clicked on a megathread 'til a few months ago, my brain just blanks out the pinned posts.
