I had the complete opposite experience in DC. There are a TON of startups in DC. Far more than where I live now (Portland OR). You should checkout über offices. They have 5-10 startups working out of all three locations (most of with funding). On top of the co-working/startup spaces you have other accelerators and funding opportunities like 1776 and Acceleprise. The DC startup scene is definitely healthy.
