So, for example, if I wanted the specific answer to a more difficult or specialised question which would be known by only a limited number of people, (or if someone did research). An example question might be, who are all the companies in Europe developing thin film solar technology? Another example might be can someone tell me the 5 biggest manufacturers of bathroom tiles in the US? Sure I could research this and find it out, but if I was willing to pay for the answer is there anywhere as efficient as Yahoo answers I could go..?
