No, not at all. For one, there is no difference when it comes to new users. The difference is that Linux lets you get at its technology if you want to, unlike other operating systems. This tends to create the impression that Linux users need more technical help, but that is not really true. In fact, we rarely have to resort to the phone.
Most support happens via e-mail or via the web.
Very rarely does one have to actually pick up the phone and call someone. These people are in for a rude shock when they find out that practically all support for any application happens this way now. I see tremendous potential for Indian programmers to contribute to Linux. Unix is taught at university level, so most people are exposed to Unix programming at every level of their technical education. This is what makes Indian programmers so desirable in the US and Europe.
