It's really just a matter of sitting around with friends and brainstorming. The only thing that really matters is if the domain name is open. Having a .com domain isn't as important as it once was. You can also use tools like http://www.panabee.com/

Just be careful when you're checking the domain name. I've heard of companies (I won't mention any because I'm not 100% sure it's true) that will purchase your domain name in a few days if you don't buy it. So if you find something open and even think you'll use it, spend the $10 now and secure it. My $0.02...

I can't point to any conclusive evidence of this, but I'm convinced when I used GoDaddy, they purchased the domains I tried a few days later. Based on that, even though it is inconclusive, I'd recommend using someone else when checking to see if the name is taken.

I believe it. Which is why I only use namecheap.com for my searches.

F*%k GoDaddy. You too Bob Parsons.
