I have stayed away from it for a while, but after my partner switched over to it I decided to delve deeper into it. The openess of Bluesky to developers is a breath of fresh air and the platform itself has some really great features. So I guess you can say I'm a fan now too.
I was also able to create an app on Bluesky that grew to 15k users in less than a month[1]. The Bluesky team was really open to helping me with some rate limits to make sure it could continue running well too. Reddit and Twitter probably had similar vibes when they were starting out, perhaps Bluesky will face the same fate, but there are no guarantees with any platform out there.
