Has anyone ever tried out the Oracle at Bacon? http://oracleofbacon.org/
So you put in two names of actors (say Alex Trebek and Sasha Grey) and it'll draw the shortest path between them. Anything like this for Pubmed? Or could be adapted for Pubmed searches? Another thought would be something like a Wordle on author names to see which authors they've published with the most.
This kind of thing is more of a thought. It could be useful for finding reviewers who are perhaps more independent in a narrow discipline. I like the Pubmed2Wordle App that Andrew Su made some time back: http://pubmed2wordle.appspot.com/
