Why blog?

As an avid blog reader, I guess it should have occurred to me before now to start one myself. I guess I'm not so concerned with anyone actually reading this, I just think a blog is a good way to record my thoughts on library instruction and information literacy as I have them. I often have good ideas (or at least I think they're good ideas), which I promptly forget. Hopefully, this will help with that. Also, since I'm a confirmed lurker on many blogs and listservs, I want to use this space to react to things I read elsewhere. We'll see if I actually do that.
