Not sure if this'd equate to feature creep or not but it'd be useful to know what category people submitted a link to in addition to who did it first and how many followed.
When you're on a site you can also get to that info page about the site by clicking the "shared by (n)" link in the sidebar. (where n is the number of people who've shared it.)
We should at the number of shares and the first share to the info page. Thanks for the feedback!
