Well, you have well over 300 posts, and i see you post around a lot, so I'm not surprised people recognize you.~ I lurk more than anything, so I'm a bit of a ninja and nobody knows who I am. |D
I'm like that too. For some reason when I see a familiar name I get a surge of happiness. Maybe it's just the feeling that people aren't unique to one place that makes people excited. Seeing a random username on a random website is one thing, but knowing that the owner of the name moves around and is present in many places as a real person is, I guess is just the cool part.
