Blogs have been around for years now; years longer than I knew about them, that's for sure. In the past few years, the internet's gone nuts with them. They're all over the place. But you already know that.
So maybe someone could explain this to some media types. I'm too lazy to go looking for more examples than THIS, but I've seen the phrase "web blog" more than once lately. And it drives me just as crazy as when some says the phrase "PIN Number". So, for the record:
Blog = web log
Web Blog = You Look Stupid.
