I just started, but on my uploaded products thus far, I strained my brain looking thru the catagory list trying to find exactly what catagories my product fell into, cuz I thought it WAS part of the criteria (and so they showed up in the right searches)
but yeah, I do agree that people need to catagorize their stuff properly.
