Thing is though, n00b, it took me about 5 seconds to download the wallpaper and about another 10 seconds to look at it and type up a review. On the other hand, it took me over an hour (I can't remember exactly how much over, though) to review the IC battle pack, and a LOT more thinking and such too.

The point is, your comparison to your upload and other level uploads in terms and all that stuff you said about the numbers of reviews etc. isnt entirely accurate. Anyone can take 15 seconds to look at a picture and post a witty (or not so witty) comment in reply to it, but not everyone feels like spending an hour to play through and criticize a level or level pack.
