Its all very interesting is all this, but do you not think that shared server serve a purpose, to my mind it gives joe average a chance to stick his toe in the water of having his or her own site, to see how he gets on with it without having to fork out a fortune each month for VPS and so on. I suspect not everybody is up to running there own server anyway but i know some you can get managed for you.
Saying all that though, The issue with shared servers isnt really about them saying unlimited diskspace see more and so on, because if you build up slowly, you can have as much space as you want, the real issue i think is CPU usage, this is what limits you, usually it is set really low like 1 or 2 percent, so if you go over this usage at one time, this is when their alarm bells start ringing. Its true that its all a con trick though one way or the other they are trying to scam you into believing you have something you haven't, and ive been saying this for a long time, there really ought to be some regulatory commission that keeps an eye on these people, because at the very best its false advertising, to just out right criminal behaviour.

I think for all of us that use shared servers, we are going to get screwed over one way or the other, you just cant win really.
