A Sub-forum for pinned topics

I don't know how useful it would be and perhaps this is a good or not-so-good request however I've noticed we're really stocking up on pinned topics and wondered if it would be better to create a sub-forum for them in each unique forum area.

For example opening the Discussion and Software forum area the pinned topics take up a good percentage of the screen space versus new and on-going topics.

Just a thought!
