To be more specific, this could apply to the following forums and disciplines: Technology (programming, web development, hardware), Graphics (graphic design, art, image manipulation), Music (diy, relevant software).
I think this would foster a more industrious community (not that this site doesn't already have talented individuals), and may increase activity on their respective forums (if for instance, someone reads a guide on figure drawing and is motivated to draw and consequently post their attempts).
Points against this: The information in these threads may repeat the information on other sites, i.e. the chans (this is perhaps a moot point, as people might be unaware or unexposed to such resources), and of course people have to actually take the time to put such threads together.
