I've been pulling my hair out trying to come up with a domain name for my upcoming social bookmarking web app I've spent hours on thesaurus.com trying to find an unusual name that hasn't already been registered. I've even tried almost nonsensical spellings only to find they have also been registered. The only half decent name I was able to register is a .in domain.
I'm trying to figure out if it's worth building a brand around such an unknown domain extension. I know pinboard.in is fairly successful, but it seems they target a more tech savvy audience that's less particular about such things.
Are there any successful, mainstream web sites using ".in"?
