Everything you could possibly want to know about Saimoe is here.
It's Summer Comiket, which means that the brackets for the Anime Saimoe Tournament (not to be confused with International Saimoe League or Korea Best Moe or the now defunct SaiGar) finals have been drawn.
Eligible characters must be female and have appeared in an animated work released from July 1, 2010 to June 30, 2011.
You might be able to vote. I've tried, but I think my ISP was banned for being foreign. It's complicated too, since you need to hunt down 2ch threads and get voting codes and such.
Matches for the finals start on the 16th and should update daily around midnight JST.
I have no idea whether anyone cares in the slightest about this, but just in case, here are my picks anyway.
