Well, there's some interesting stuff on the net to be found regarding
twitter and analysis:

http://gephi.org/2011/the-egyptian-revolution-on-twitter/

I'm using gephi a lot recently, mostly because of a project for a research group
at the university of Amsterdam that i work for part-time. I'm also diving into
Maltego, which is a non-open tool to do interesting things with. Both do lack some
more advanced network analysis methods though, and i'm looking into extending for
eg gephi. I know the Maltego folks are interested in such stuff as well, but well
it ain't open source so i can't contribute to that :) I am writing some transforms
just to play with it for Maltego though. In fact, we're doing a hackathon re that
soon:

While it is scary knowing that government agencies, corporate marketing departments
and intelligence agencies are doing the same, it's both interesting and useful to
see what you can deduce from stuff people carelessly dump online.

It does a great job with both mutative and generative fuzzing algorythms and is Python, so it's very cross-platform. Next step is figuring out getting debugger information off of VMs in an automated fashion. It's fun stuff.

Interesting, managed to find some interesting responses yet?
