Startups in DC? 
eli: Net2DC (http://www.net2dc.com/) focuses on non-profits, but they're affiliated with http://affinitylab.com/ which is home to several very early-stage startups.In the past, I've also seen several Dupont-area startups hiring on Craigslist. I assume you've already looked there?And maybe it would help to narrow your search a bit. I know there is a active Drupal development community in DC and I believe the Rails user group does meetups as well.
