I used to be obsessed with the real estate section of Craigslist but it got to depressing (both with low values where we live and high values where we want to move to!)
I'm completely addicted to etsy. I have "hearted" stores that I practically stalk for new items (mostly sewing patterns) I might even open my own
My other thing is my RSS reader. All of the fun crafting blogs in one place. I'm constantly hitting refresh. I had to "turn in" my laptop to my husband for a few hours yesterday so I could get some laundry done!
Oh, and Flickr!!! LOVE Flickr!!!
