It's a lot simpler than Facebook. There are no groups, no marketplace, no dating, etc. You sign up, and either post content, or don't. You choose accounts to follow so that when you get on there to scroll, you see their stuff (in theory). After years on there with diverse interests, I follow more accounts than I could possibly see all the content from. If someone comes to mind, I can search them and see what they've posted that I've missed. Of course there are suggested posts and ads and such that are presented to you that you didn't request. Facebook is much much (MUCH!) worse in that regard. I think about deleting Facebook except I like the hobby groups and have started to use Marketplace more recently.
