Superb paper on Social Bookmarking

If you are doing a start-up you better add the “social” moniker to it, to attract VC funding. Jokes apart, the social bookmarking scene is looking pretty good. If you could read one paper and  become a social bookmarking whiz, this is it.  Its a 2 part article – 2nd part is here. Great job Ben, Tony, Martin and Timo.
