Uploading Music Videos

So, I just uploaded a video to YouTube (musicman0494) in which I sang "Fireflies" by Owl City. The reason I occasionally will post one or two videos of me singing is that I enjoy it, and I think that some people enjoy hearing it (although I do tend to drive my family crazy sometimes). What are your feelings about video uploading? Do you use sites other than YouTube? What types of videos do you post?
