Well, some of the tips maybe are good but I beg to differ with the first. You can't say a host is overselling or they are a bad host just because they offer you "Unlimited disk space", "unlimited bandwidth" and other unlimited features like emails, databases etc. Some of the best hosts are offering unlimited disk space and bandwidth out there, or just a ridiculously high amounts of disk space and bandwidth. Does that mean these hosts are crap? No.
The "Unlimited" thing in the hosting business works this way. The hosts as well as you know that you are not going to use 100's of GB's of the space or bandwidth per month. Most of the "unlimited" offers are backed up by CPU resources restrictions and other restrictions in favor of the hosts. Even if you still have 90% of your disk space and bandwidth unused in your package but you have crossed the limit of CPU resources usage, they are either going to tell you to move to a dedicated server or suspend your account. That means you are never going to get to use around 90% of space and bandwidth with those shared unlimited or shared (ridiculously) big hosting packages. So, in my opinion, all those big hosts which offer you these unlimited packages just calculate how much DS&BW you are technically allowed to use per account and put a specific number of accounts on each server to ensure better hosting.
I have just noticed Hostgator, BlueHost (also HostMonster), LunarPages are all offering unlimited packages at the moment (didn't check other hosts). Does that mean they are crap hosts? No. Most of them know what they are doing and they have their own calculations. The "Unlimited" thing is just sugar coated words to attract newbies but it may not necessarily mean they are crap or scam. Also once you are into the business you would understand how painful it is to leave all those DS&BW resources unused on your servers if you are not going to oversell even a bit. To be frank, with genuine hosts (which know what they are doing) you can't use the word "Overselling" it's more like "Utilizing unused resources".
Just imagine you have got a 250 GB disk on your server and you have sold 25 accounts each consisting 10 GB disk space. Do you think all those are going to use all the 10 GB on their accounts? Can you even say they (on an average) they will use 1 GB out of the 10 GB? Let's imagine each one of the 25 account holders have used 5 GB. Then what about the remaining half of the disk space of the disk? So, with a strategy and some calculations, you can oversell. But that shouldn't be "OVER oversell".
