I'm also really late to the party, but you should check out spngenlove, which was a gen rec community that was extremely busy and popular there for a while. It kind of died in season 5, so it doesn't have any of the newer stuff, but it's a great resource. http://spngenlove.livejournal.com/tag/theme%3A%20delighting%20in%20dean is all the recs that came in during dean-focused rec'ing weeks (though I'd check out the other theme weeks too...you won't be disappointed.)
