Lots of people I know have been streaming onto Bluesky. My main venue for public microblogging has been my Mastodon account at mathstodon.xyz/@mattmcirvin for a while, but I have now given it a Bluesky mirror at mattmcirvin.mathstodon.xyz.ap.brid.gy, and Bluesky folk should be able to follow me there. There is not a lot there yet since it just started mirroring. We'll see how well this works.
