This is a common question that I see people asking everyday, and one which is pretty easy to answer. It is not that setting up a website or dealing with a technical problem is all that difficult, it is often that you do not have the technical resources to get from point A, which is the problem, to point B which is the solution. And even if you do have the resources available, you can still be overwhelmed by the amount of materials that you have to look through in order to get to point B. But perhaps the most frustrating part of any problem, is when you are presented with the solution, but have no idea how to get there!
This happens so often in the technical world of computers, that undeniably I have come across multiple situations, where I literally gave up and went another route entirely because even though the solution was right there, the amount of steps involved to get there would make the whole solution no longer worth the time and effort spent.
And so Support is important not so much in solving your problem, but in helping you get to that solution.
