There are a lot of pointless comments on apps that are just a waste of time. There needs to be a rating system or some other way to stop all the spamming and comments that are not even remotely related to the product.
I assume that is coming, along with moderated comments, when the Market is updated next year. The basic nature of it will change when developers start charging for apps.What we REALLY need is a decent desktop way of browsing the store.
