I need an advice about the best way of using sub-categories and/or tags.
Actually I am filling a computer related blog that will have posts containing reviews, articles, software.
I wonder if I should use sub-categories and/or tags.
For example I have created "reviews", "software", "articles", "web sites" root categories and have also created sub categories for each root like reviews/security, software/security, reviews/internet, software/internet, software/benchmark and so on...
But is it good to also create security, internet, benchmark.. tags or should I create only root categories and use tags for each sub ?
