Well, also maybe Reddit, unless they’re also removing/burying other social sites. Besides that, any messaging services one may use to chat with friends or others.
Echoing this, with some slight adjustments:
Promote the specific sites/communities to people, and on sites that permit it, share links back to specific posts/comments that you found interesting/amusing/etc. from said sites/communities.
Reddit got popular off the back of changes to Digg and people mentioning/sharing stuff from Reddit there. I’d imagine TikTok also grew in popularity from people sharing stuff from it on other major platforms like Instagram/YouTube/Snapchat/Twitter, much as now RedNote’s growing in popularity from people mentioning it on TikTok and other platforms.
Talk about a pleasant surprise!
