I know I'll probably get downmodded for this as it's a bit tangential but I'm of the view Justin.tv should rename and rebrand itself. It sounds like someone's homepage and it's origins are based around the founder's personal video channel. It just doesn't sound like a site where people can share video themselves and doesn't reflect what it has really become.
I can see where you're coming from, but we've built up a lot of brand equity in the Justin.tv name now, with tons of people coming to the site, links, etc.
For more and more people, it's just a name, like "Fox" or "Warner Brothers". Most people don't even know about the original Justin.tv show, or who Justin is.
Yeah I understand that but from a complete layman's perspective I still thought you might get a different category of person visiting (rather than those with an interest in tech). I thought you might need to rebrand to cross the chasm so to speak. I was concerned the name sounds a bit too gimmicky? I guess. But I wouldn't pretend to know more about your company than you though so if it's working out and you can build the brand name go for it!
There's nothing wrong with having a brand name that doesn't explicitly say what the company does (reminds me of the Forest Gump quote "We invested in some apple company"). Their site get millions of visitors per month; they'd lose staggering amounts of brand equity at this point by changing names. Besides, I'm willing to bet that the vast majority of its users don't know the origins of Justin.tv.
I wasn't suggesting something generic. It can have as much character. I just get the feeling from Justin.tv that it is a) some new web service that is probably going to fade with trends and b) has nothing for me unless I like justin, whoever that might be.
Just my 2 cents anyway.
