Does Mendeley allow you to follow the publications of researchers on a paper-by-paper basis like this simple app myPeers (http://codingseed.com/) or is it mainly for recommendation of papers based on matching key words?
I'm VP for new product for Mendeley. We don't have the ability to follow a specific author, yet. This is something we are working towards, and will hope to have available in an upcoming release.
If you'd like to follow the publications of a certain author who's on Mendeley, just add him as a contact and you'll get a notice when he adds new items to his publications list.
