I wish there were more porn days, because you're right -- this is an awesome way to dip your metaphorical bits into a new fandom! I made lots of new friends and found lots of fun new writers yesterday.
The best place to find a good cross-section of good fic these days seems to be on Del.icio.us, the bookmark site. If you want to start with mine, it's
http://del.icio.us/theantijoss. Then poke around my network friends and see what they have bookmarked.
It's an older fandom, but it's a great one! :)
