Fanime! started today, and I am currently en route to San Jose for that very reason.
As previously reported, Jon went in 2009, convinced me to join him 2010 (to which we did a five part followup), and I went last year.
This year, Jon and I will be there for the whole convention. The show is fairly inexpensive (though prices have been raised from last year) and a single day pass is between $30 and $45 depending on the day.
If you are still waffling about attending, take a peak at the schedule. Speaking of schedules, I have been assured that this year there will be pocket schedules. It seems that the staff heard the outcry of the attendees.
