The domain is already attracting a good amount of traffic for a fairly popular application. He's already registered a bunch of domains to keep the squatters at bay - the question is really whether he should renew any of them or none at all.
Can't he just check his weblogs then? Have a look at how many people actually come in on those already registered domains and keep them if it's anything significant.
This is the kicker - when he registered them all he didn't think to install any analytics software. He has done it now just in case but it's not much help.
Are they .com's? Its probably worth the $10 a year just for peace of mind. They're not a massive outlay if you only have a few of the most obvious ones.
I'm actually asking this for a friend of mine.
