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.
erin, I'm really interested to see what the top sources are. My guess is that the top ones will be users of Hubski that have blogs or web-sites. Beyond those though, I really have no clue what will be the top. Great suggestion. As for the guilt from being a developer requesting development... well, that's really how the coolest ideas tend to come about. No guilt needed. (says the guy on the team that's not a developer)
