TikTok is one that I just haven't ended up getting set up. I think my wife uses it, but it won't let me pick a username that doesn't suck for some reason (keeps telling me it's already taken even if I put in literal random garbage). And as I don't want to use their default, I just haven't finished setup properly. But, that said, I'm glad to hear it's going fairly well for you. I hope you're able to slowly gain more of a foothold!
