Twitter - I'll be live-tweeting as long as the wireless network plays nice. Last year, it was a bit overloaded but I was also using AT&T last year. Verizon > AT&T. Follow me on Twitter to keep up on SDCC fun and some panel coverage.
Facebook - This is my geek with curves fan page, and I'll be uploading photos there or posting a link to my Flickr account nightly from the convention.
Geek Girls Network - I've installed a Wordpress app on my iPhone and so have the other writers at GGN. I might do some quick posts while I'm waiting in one of many lines.
I'll post recaps of each day starting next Monday.
Shockingly, I'm not the only person talking about Comic-Con. Follow the #SDCC hashtag on Twitter! I guarantee it will be buzzing. To hear specifically from the League of Extraordinary Ladies, look for the #lxlsdcc hashtag. If you have a panel for your favorite show that you are bummed about missing, just keep an eye on YouTube the day after the panel is scheduled. It will probably show up.
