Video Blogs

Ok..so I've been looking at youtube video blogs all day. The ones that inspired me the most from youtube were 'mememolly' and 'paytotheorderofofof2'. They come up with the most interesting stuff to talk about and I basically just enjoy watching them. I am now inspired to make a video-blog but don't know what I could talk about. Any ideas are welcome. I'll research into it more so I can get a better idea of how to go about doing it.
