I bring this up because indeed .org tld is used generally for non-profits, or the non-profit/philanthropic arms of for-profit companies (google.org, etc.), so branding .org tld for your little startup would seem like a misguided decision, and may possibly impair the professional look one is going for. I know you've just said that this is an attractive option where brandability isn't important, but I'm hoping you can discuss this just a little bit more. Is using .org for one's startup a total no-no or is there some conceivable scenario in which it would actually work out?
