I've been in the area for about a year now but still have trouble finding interesting things to do week to week. I used to live in Seattle and I had a collection of blogs I would follow that would usually tip me off to cool events.
Generally, what DC blogs do you follow to keep up with what's going on? Right now my consumption is basically just Prince of Petworth and DCist.
Edit: Alright! This has been great. Here's what is in my Reader right now. If more come in that I end up adding I'll put them up here.
Unsuck DC Metro
Greater Greater Washington
Prince of Petworth
Brightest Young Things
