Domain Pigeon was recently mentioned in a Smashing Magazine article titled 10 Tools For Finding, Registering And Managing Domain Names:
Domain Pigeon’s approach is different to the search tools mentioned before. It automatically generates lists of available domains as well as Twitter names. The names are displayed in different colors, depending on how many people have showed interest in a certain term. The darker the color the more popular the name. You can also order the lists by length, popularity and show only domains or Twitter usernames. Examples of generated domain names are ablebo.com, meliori.com, minecafe.com or shopshost.com.
Domain Pigeon is an ideal source of inspiration for domains and short available Twitter names.
