bit of a 'best practice' question, as I'm very sure there are many ways to do this sort of thing, but...
When/how do you decide whether to use a section, category, or entry type to organise your entries? I've been finding that my EntryTypes match 1:1 to the categories in my 'global' group, and that's lead me to wonder if there's any point in having them as global categories too, and whether I'm just not understanding how to use these tools properly.
For example, I've got sections: webDevelopment, generalWriting.
And categories (in a global group): Article, Tutorial, Links.
And EntryTypes in each section: Article, Tutorial, Links.
It's starting to look like there's little point in having global categories, but not having categories feels very weird / wrong.
So... how do you decide how to organise your stuff?
