A corporation joining Bluesky isn’t normally news, but Microsoft managed to do it in style this week. The first thing you’ll probably notice is the Windows XP Bliss wallpaper and a pun about blue skies, but if you look a little closer you’ll see Microsoft even backdated this post to its founding date of April 4th, 1975 using Bluesky’s AT Protocol. That’s the kind of nerdery that Bluesky users appreciate.
