I think it really depends. Rerouting traffic is a weird thing, but actually if you want to be taken seriously, I do suggest shunning free hosting. If you want to go cheap, Yahoo has a cheap program that's easy to set up with their site builder. Overall, I tend to take emails and websites less seriously if it's a freebie. I don't know why. If you have a charity site, you might want to check to see if someone will donate free hosting. A lot of places do if you ask.
