So, apparently some of us are special: http://knownissues.blogspot.com/2011/05/were-investigating-issue-which-is.html. So it's been a known issue since May 24. Apparently they have fixed it for some people, but I've logged out of all google sites, emptied cache and cookies, unclicked remember me, danced the voodoo dance recommended in the blogger help forums and still no luck. I've experimented with logging in as all kind of other things now, but I really want to just be able to login with my normal google account.
I know I'm whining about my free service, but I'm agitated.
