b2c: depending on your users, you may even prefer .co to .com - esp. if you target users like me. b2b: generally careful here - except if you target startups like ours.

So yeh, directly correlated to your target being tech savvy or not I'd say.

True. My assumption is that .co may be a tough sell for some b2b models. Interesting in finding if that is true or not.
