Catagories and Tags

Categories are meant to encompass a group of posts. It is always best to start with generic categories and work your way down with subcategories as your site grows. After having run multiple blogs, we have heared that blogs evolve. There is no way that you can come up with all the right categories. Chances are when starting out, you are only writing one post a day. Or maybe 3-5 posts a day. Having 30 top categories is pointless especially when some of them will only have one or two posts. You are better off with 5 generic categories that have fresh content rather than 30 top categories where the majority are not updated.
