In line with a fundamental keep it simple mentality, I’ve been scouring the web to find best practices on when to use Custom Post Types or when to use Categories. Despite my quest for solid, black-and-white answers, I have found none.
My thought at the moment is to use regular posts and categories as much as you can, and only use Custom Post Types when you really feel need to. Again, no science here, just a gut feeling that you’ll be better off at the end of the day. Take my exhibits, for example: While they seem to be a completely different kind of content, they’re actually just posts of category type “Exhibits.” Easy peasy.
