The type of people that will engage with the likely uses of the site will be able to spell it. Those who can't probably aren't your target market anyway. It's a great domain, and so much of this depends as with any domain what you use it for. The domain is merely the first step.
What never gets said, when I read posts by those who've clearly already made it, is how a good domain can open up many more lucrative doors in the future if the time and effort is put into it, and my guess is for those who've done well this is exactly what's happened. One thing led to another and the rest is hi$tory so to speak. So there's more to it than just monetization of the domain.
