Webhosting industry right now is an absolute mess. As RJ said, anyone with 100 bucks and free time can run there own hosting site.
This has got to be killing the major hosting providers massivly, and im sure they have noticed at least a small bit. The problem is, most of the time someone is looking for a professional, built, stable, and reliable hosting company that they can trust for long term uptime and support. Rather than the 15 year old kid with 100 spare dollars and his hosting site, not buisness.
All of these minor hosting providers are always competing to offer the most, for the least. For some people that just great, but for others it doesnt make the slightest difference. They are more concerned about up-time, support, reliability, and will pay the price for it. If it costs 7.99$/mo. to be hosted with a stable company that you know you can rely on to be there at 3 a.m. for phone support, and have a great up-time then most internet 'newbies' looking to host their buisness will pay that. Why? Because the need to count on that stuff. For someone else to cut down the price by 3$/mo wont make a difference to them, unless they can offer the same support and reliablility, which most cant.
So I basically think that if those minor hosting sites want to offer hosting, good for them. But be honest to your customers. If they ask, tell them how long you will really be able to be there for support, and how much up-time you will really have. People that are offering all of this 1$/2$ hosting are really bringing down the buisness alot. The value has gone way, way down while the availability has skyrocketed. And yes, it skyrocketed because of how easy it was to get started and attract your customers by offering that much lower than the competition....
Phew, thats all :D
