Having been in product management and web development, I kind of feel guilt even making a request...
What would be the possibility of creating a page that lists the most popular sources? I know if you click on the source in a listing (i.e. nytimes.com) it lists all the shares that originate from that source. It might be interesting to see what other sites or mediums (i.e. text, video) are the most popular on Hubski.
I've never taken a look at it myself. I can whip something up. I'm not sure it deserves any prime real estate, but I'll let you know where to find it.
