I know that #Threads is going to just explode. My wife installed it and is already posting.. She would have never signed up for a Mastodon sever.. and that is fine too.

I think if #Meta follows through with #ActivityPub it will be great for #Mastodon. If you don't want to join #Threads you can still communicate with ppl that would never join #Mastodon. It also provides a gateway for ppl if they want to leave #Threads in the same way ppl left AOL for the wider Web.
