I find that most people in my life have at least one "thing" they are collecting. It is often an insight into their personality and it is fun to hear people talk about something they are passionate about.
You could say I collect websites (kind of). I have the world record for the most sites having signed up for. It just sort of happened and then it stuck through maintenance.
You thought I was joking before? Well, it's true. I can't find it in modern Google, but one of the world record wikis has info about me listed under that world record. It's like my ship-in-a-bottle if you will.
