After introducing Pubmedfight, I wrote about InterMedi which:

is a set of tools aiming at connecting biomedical researchers together helping them to find informations about their previous works, collaborators and affiliations. The remarkable fact is that no information is required! Our intelligent software knows how to combine information already available on the web, specially on the Pubmed database, to provide meaningful information.

Now they have:

• Single Search: Based on co-authoring of Pubmed publications, find someone’s collaborators, publications, affiliations.
• Fight: Who’s got more publications? Whos got more collaborators? When did this fight reach its climax?
• Get in touch: Whos’s between you and someone else?

Unique idea on the life science market. You should definitely check it out.
