Nice; pickydomains is another good site to crowdsource names with available domains. Using Mechanical Turk and Soundcloud to test for "spellability" is brilliant. That said, in an age of omnipresent search, and social distribution, I wonder if spellability is much less important than it was ca. 2000.
You'd think so but a good friend of mine (hope he doesn't mind me sharing this) founded Syncplicity. A name I thought was brilliant until I saw him at a networking event:
Him: "The company is named Syncplicity"
Them: "Simplicity?"
Him: "No. SINK-plicity"
Them: ???
Him: "We're Dropbox for enterprise"
Them: Oh, I love Dropbox!
Touche. :)
Which company did you use to register your domains, and how long do you have to return the domains you no longer want?
