wiredfire, 
My hot-take on #BlueSky, as it's a lively topic:
More decentralised projects is a good thing.
"Big" (relatively speaking) names behind it can be helpful in bringing decentralisation more into the mainstream.
It's existence, or potential success, doesn't harm Mastodon, fedi, or ActivityPub.
Let's embrace the momentum we're seeing of more forces drifting back to how the web was when it was a more open, more kind, place 😁
