There was a recent XKCD[1] on pairs of words that sound good together and quite a few of those domains were available. So I don't know what it'll be yet, but my next project is going to live at lasernarwhal.com.
Lol. My surprises of the day were toogeo and talkik. I think I have a knack for finding these. I should charge. :) Ooh, talkic is even better. It's like talk and topic!
I've considered having a best available .com competition here, but think it might be considered wasteful, doing the work of squatters for them.
