In 2001, i tried to register a short name with "name(s)". Shorter was "name(s)" preceded by a vowel; but a, e, i ,o ,u were all already taken (and even b,c,d,...), meanwhile, i had the fantastic chance to register it with "Y"...
but as a site to develop, this is easy to remember by everyone, with "Y" a symbol of many concepts/words/things, like Yankee, Your, Young, Yes, Year, etc..,etc...
Ynames.com = Why Names? A site that deals with the significance of names, perhaps the significance of domain names -- I ll leave this up to you Frenchie.
Me thinks this sounds better than "Yellowpolkadot Names" or any other arbitrary "Y starting-word + names.
