Most appropriate for this blog is definition 3:
"(colloquial) A person intensely interested in a particular field or hobby, generally at the expense of broader social interaction. Often used with an attributive noun."

I've been called a Computer-Geek, a Coffee-Geek, Bicycle-Geek, and more.
Hopefully you'll identify with some of my passions, and be able to avoid some of my failures!
