It's funny to some #Mastodon and Bluesky users that say (rightly so) "these are good numbers" with thousands+ new users come to their platforms per week but poo poo Meta with it's 70+ million with #Threads (which I don't have $0.02 on yet).
If you don't care about your social network size, then not sure why either would matter. Personally I'm interested to see what happens when/if Threads joins #Fediverse. Until then I'm excited to see people exploring – reminds me of the early web 2.0 days.
