Are there any Bluesky users or feeds that are worth following?

No. Twitter wasn't, Bluesky isn't worth it.

Bluesky people are the people who think the internet should be censored. If you quit twitter after Elon Musk took over, meh. If you start to use the PDF network :P That's troublesome. No there is no body cool on bluesky network. They follow the wrong people themselves by joining that network. Must not think about following them.

While devRant is not that big, it for sure is the best network to follow.
