For iOS there is quite a few websites providing a alternative ways to browse through the many apps and also provides neat info about it's popularity.
What websites are there for the Mac App Store?
I already know of AppShopper.
The reason I'm asking is because I wish there was an "add app to wishlist" feature and a way to see comments across the world and an easier way to look through the lists beyond the limit of 50 apps (I know of the See All, but..). And for a lot of other reasons.
