The RubyGems dot org dashboard, as also the atom RSS feed of gems published by an owner, has been fixed! It broke about a month after the hostile takover, and then stayed broken for about 4 months. I published one gem per day, on average, during this period.
Congrats on fixing it RubyGems skeleton crew!
But come to think of it, I have published ~ten gems since that one on Wednesday, so nevermind. It is still very much not working, only now it's not working in a very strange way...
