I can't believe they were still running a rails frontend til now, to be honest. I thought rails had fallen out of favor at least 5 years ago (deservedly in my biased estimation). We'll see what happens with Github. I don't have any use for the new bells and whistles like editing the repo directly from the webpage (scary!), or deeper VS Code integration. I'm not interested in Co-Pilot, though a co-worker told me the other day that it had saved him hours in a particular instance.
I just hope they don't kill the parts that I think are useful, and the things that made GH so valuable in the first place. It's a worrying trend that software seems to get worse for users in the name of making more money.
