Recently I have been looking at how we measure contributions to science in a way that is more well-rounded than the h-index and similar initiatives. Most of this relates to how we measure a user's contributions to projects such as Scratchpads, ViBRANT and eMonocot.
The "alternative metrics" movement has been around for a number of years now, and one of the more established outfits is Altmetric who provide badges for research articles showing how much attention that article has received on a number of purely social (Twitter, Facebook) and 'academic social' (Mendeley, Connotea) networks.
As the badges are pretty easy to implement I have made a small Drupal module that displays an Altmetric badge on Biblio node pages, and provides a configuration page to allow the badges to be customised. The module is available here: Drupal biblio altmetric.
