Is there a place where people can post their ideas for software applications? I'm constantly thinking up things that I don't have the time, skills, or knowledge to implement. Reading the techcrunch piece I just thought of this one...

Crop tester; An application that lets farmers and agricultural scientists share techniques to increase crop yields. Inputting crop type, soil, climate information, the farmer could get ideas to test on a small portion of the crop. Feeding the results back into the system would help create a massive, public database.

Maybe the ideas is good, maybe it sucks. But it would be nice to have a site where ideas could get posted, then voted up or down.
