Exclude post formats from categories archive

This simple question is actually a good one. The posts and there now myriad complicated formats seem to be a hack to allow different sections – especially in the home page. However, I have yet to find one client that can adequately get their head around the formats and use them. No one I know uses them – too complicated and unwieldy. I don’t think post formats are going to last in there present form much longer.

How I get around the issue you are raising is by having a separate category for this (gallery, aside) content. That way, when you enter the category archive, it does not show.
