I’m going to reprint some advice here that I shared on bbPress.org as there is a great deal of confusion and misguided ideas over how to find a good host for WordPress or bbPress.
A quick google shows there are dozens of “Top 10” lists of hosts. Some are dubious with commission links and others that as well intentioned as they are, focus on non-technical aspects that don’t matter much in the end.
There is a MASSIVE amount of competition in the hosting world and virtually everyone offers things like “uptime guarantees” and seductive low prices to try to grab customers. In the end it doesn’t matter. You can go with a provider that’s been highly recommended and have the worst experience, or try one out that others have complained about and have a good experience.
