Weeeellll, I can kind of see his point. I spent my holiday Stumbling (stumbleupon.com) and found it chowed my bandwidth significantly due to lots of images and videos downloading. That being said, it depends on what kind of Web2.0 application you are using. But, yes, I agree with Uno. Its the local cap, not the general cap.
PS. I hate the fact that we in Africa need to worry about crap like bandwidth usage. I hate it to have to monitor my usage daily as if I do not have enough on my plate already.
