I like it. You should develop it. We need more good DN sites. I'm sure you'd make a quality one. Perhaps it would become profitable and fun or you could sell the dev. site. Undeveloped you could maybe get $25 from a domainer. The plural might make more sense. Good Luck.
It's a nice name! Limited audience (domainers) but very useful and easy to remember. Worth developing! Hard to put a price on it, as the real value will rely on how it's developed.
