I have some interesting tags stored on Stack Overflow with * in them (e.g. c#* or delphi*) and they no longer seem to be working. I'm fairly sure they did since I remember setting them up after reading this blog post about when they were introduced. I just get a completely blank page when clicking on them.
I've also tested storing interesting tags on the other sites with * in and they all seem to be affected. Am I missing something here?
