This week we begin a new way to show the best sites, we're categorizing them, because a lot of users asked me why I've chosen those sites. So I decide to divide and list the best sites I saw in the past week, split them and put each one under a category name. But feel free to give me some advice on new categories or some site to be featured in the next list!
