I have a really bad addiction. And that is to fonts. I can spend hours going through and installing new fonts. Right now, I have about 500+ installed, with about an equal number backed up for safe keeping. For what, I'm not sure, because I really don't end up using them all that much; more than some, less than others. But still, it's a very comforting feeling for me to know that when I need it, when Lucida Grande is just not cutting it, that one specific font will be there for me. It's all really disgusting, really.
