In the overall scheme of things, I guess AMA is still small potatoes compared to the exposure GP and WSB get.
The UK for example is bike crazy compare to here. For a lot of people there it is their only means of transportation. The knowledge of bikes and the history is incredible. Spain is supposed to be even more bike crazy.
If anyone ever wants info about bikes, I always direct them to some Brit forums, cos they know so much about them.
