Of all the things I saw this week at Social Ad Summit, OMMA Global or Web 2.0, I actually liked Spinscape the best - it's an collobrative Mind Mapping platform that also is able to plug into Google, Amazon and perhaps soon, your own site or database.
While I just activated my account and I'm playing with SpinScape, I haven't mastered anything about it yet - but I did make a video of what SpinScape.com can do while at OMMA Global this afternoon - I think it's work watching in it's entirety.
