Sometimes it's tough to find a new domain name. Domain Pigeon lists available names, sorted either by date added, alphabetically or by most popular. When a meter shows the name's popularity and double clicking will show how many people are interested. You might not find the name you want, but it's a nice way to see what others consider a good name and, if nothing else, a way to get inspired to find a new domain name.
This service will do one thing exceptionally well - cause people to build domain name portfolios. And it couldn't be said better, than a testimonial of sorts on the website. "Just bought ReplaceText.com. Not sure what for, but, seems like it could be good for something..."
