My thought is that you have to start someplace. Generally all I stumble across is a one line item about current prices. The rest is implied for a knowledgeable audience (which Wikipedia is not for maple syrup, I agree). This, in turn, attracts other data for comparison. The alternative (as mentioned above) is a robust article which I am too lazy to flesh out. I do start articles, but once there they provide a convenient uh coat hook to paste other information as encountered in the media. Footnoting and objectivity is the main problem. I agree that readability for one point of data is a bit, well, jerky, I suppose. But this is a lot different from pov, or, pr, unreferenced, or any of the other stuff that the noprices was trying to avoid. 

While we are trying to make things presentable for the reader, we also need to consider the editor. Things have to be easy for them, as well. The harder it is to contribute, the fewer contributions.
