I came across this review. Host monster is not good enough?
Webmasters that have had a negative experience with any given hosting company, usually are very skeptical about offerings and when they read that Hostmonster offer unlimited disk space and badwidth, they ask if this is a Scam.
In this review, Host Monster went through a lot of critique for stating those things, and if you look at the offer literally it is a scam because no resource could be unlimited. However, they offer such a huge amount of resources to every client, that for most of them, there are going to be practically unlimited.
If you have a huge site or a complicated site with a lot of CPU usage, then you are probably better searching for a more powerful solution the shared hosting offered by Host monster.
