Wouldn't that make it a minimal quora/SO that you don't have to specially post your questions on?

Or, and while we're at it — location filters for location-based questions would be the greatest (although much more hard to implement) feature. I don't want to answer someone's question about his homework, clearly directed for his friends, but I would gladly give advice to a tourist who found himself in a place I know.

I think that the system requires some form of filtering - be it by location, score, hashtag or otherwise. A featured which allows a user to get to the questions they can answer quickly is definitely something that needs to be developed.
