Very nice project, thanks for introducing me to IBM Watson. I will also play with it a little bit:) I don't know how it determines Openness and stuff, pasted one of my texts in there, it gave out 'interesting' results:)

Yeah, we couldn't find any proof that the results are meaningful in any way, but I think it's a fun tool nevertheless.

One thing I know for sure is that Watson doesn't recognise irony - I posted this poem and it was marked as "cheerful" and "optimistic": http://bukowski.net/poems/a_smile_to_remember.php

My idea is not that difficult to get to MVP, but here it is anyway: In a nutshell: an inverted ecommerce site, where you ask for the best phone under $200, no contract, and this and that are important to you, and people bid and tell you their recommendations and why (along with buy links / affiliate links).
