IDK, I don't think most people actually think about .com standing for commercial. I think most people will default to .com because it's what they associate with any website.
I'm not saying sites haven't succeeded with .net, I just think it looks like you couldn't get the 'good one.' Y'know what I mean?
IMO, .net or .tv or whatever work best when the name of your site or it's content would make having it be specifically better or easier to remember. For example, my student loan is through a company called Nelnet and their website is nelnet.net. That makes a lot of sense to me because it makes it easier to remember.
But yeah, neither's gonna do you any good or bad without marketing it properly. Do you feel like sharing your site name/url? Or is it top secret, atm?
