Collaborative Social Network Visualization I do movement building work for Effective Altruism (http://en.m.wikipedia.org/wiki/Effective_altruism), and would like to level up our growth strategy. It occurred to me that a social network visualization tool which allowed us to strategically find and recruit new influencers/donors would be mega useful. I'd love to find something (preferably free), similar to InMaps, which would allow us to:


Combine all of our social media connections into a single map
Easily see who the superconnectors are
Weight each person by their degree of social influence (perhaps some function of things like Klout score * amount of social media connections * number of Google mentions, etc) 


Does such a thing exist? If not, is anyone interested in pro bono work for an amazing cause? =)

Disclaimer: I am a data science noob, so preferably the solution would be one with a nice GUI and minimal involvement of R or Python.
I think Gephi, an open-source visualization tool, would help you a lot. Actually, as I know, the InMaps and its community detection algorithm are same as the Gephi's.
