despite all the glowing praise, hostgator suck. They ban you for even imagined infringements, and you get no warning. they just turn your sites off. still, for $10 a month, what do you expect?
more importantly, google also has a real down on the ip blocks hostgator use, because so many spammy sites live there. hostgator = the original 'bad neighborhood'. I got that from matt cutts at a party last year, and no he wasnt particularly drunk.
