While I'm usually willing to blame Facebook for most of the world's ills, as far as I can tell, this one is a Google/Blogger issue. :)
I've read other blogs have been experiencing similar poll problems today - it doesn't seem to be anything personal!
I have experienced the same this morning, about 27 votes vanished in the void -.-''
