* Marketplace was a huge success in terms of subsuming Craigslist. The quality of posts and the volume of postings makes me rarely even check Craigslist anymore.
* Small forums for various hobbies are almost entirely driven by Facebook groups now, instead of in the past where you’d find some custom bulletin board where the last post on most subforums was 3 years ago. It’s better than Reddit for certain things. Groups for communities (ie: your neighborhood or small town) are thriving, too.
* Messenger is the sole mechanism I have to keep in touch with friends from school that are now back overseas.
I think their general success is assured, even if the metaverse isn’t ready yet. They can afford to lose some money on a big bet.
On the other hand, I think that they missed the boat with the metaverse not being a big thing during covid lockdowns, because the cultural rebound of covid yields zero appetite for virtual existence. People want to make up for lost time.
