Thanks! Also, this seems as good a time as any to bring up Maltego. It's an OSINT network analysis tool that is as good as anything I know about in civilian law enforcement. You get some really cool results when plugging in Twitter data.
I looked into the tool and realized I'd seen my Information Assurance roommate use it 5+ years ago. It was a great application then, but has become even better since. I played around with it for a couple hours yesterday, lots of fun.
