I went from probably 150-200Hrs/Mo. To about 5.
I know I cannot be the only one. Reddit will live on; but technically so did MySpace.
As for Twitter I'm one leg into Mastadon, but the space flight news folk is still on Twitter.
Although tbf it’s probably accelerated the shift in Reddits demographic from users that post longform content to more casual users that just browse and upvote/downvote stuff without engaging beyond that. I doubt they care much bc they probably just want ad impressions and to become a titan akin to Facebook/twitter/etc. it seems short sighted but growth at the expense of community seems to be a common theme of vc backed anything
My reddit usage is now about 5% of what it was before. I also use it for Ukraine info, but now I do it at home on old.reddit.com, and not doomscrolling on mobile throughout the day.
