I use dreamhost. Why? Because a while back they did that 777 deal, and I posted about it on a few forums, and ended up with like 250 primary referrals and 200 secondary referrals.

So basically I get paid money to host my stuff with them :) I made like 3 grand from them so far.

Also since they bump your storage/bw every week, at this point I have 10TB Bandwith and 500GB hosting. Which isn't half bad.
