What I love about blogging

What I love about Blogging is that so many people are doing it. I just spent the last hour finding things out about old friends and acquaintances. I love that my college was small enough that I can find all sorts of people just by clicking links and following trails of friends. It's also fun to know that I can keep up with my friends from here once we move too.
The only thing I don't like is the debate to comment or not to comment. I spend time wondering if people I was not really good friends with are going to think I am strange to look them up after all this time. But to tell you the truth, I think it is neat to know that friends old and new, both close and casual can find out about me on the web. So no matter who you are, if you want to comment please do!
