[wp-hackers] WP_Query filter posts by role

[Kevinjohn Gallagher]

I think this is a great example of where the 1 to 1 relationship of WP > User is not as flexible for today's market as it could be.The binary segmentation of Logged in / Logged out works for blogs, but as soon as you move away from that you start to hit issues.bbPress and buddyPress are great examples.

Just my two cents.
