Vlogging and online instruction

I can't help postulating about the possibilities this new, easy to use format opens up for online library instruction. If one's library already had a Blog, links to Vlogs on the use of different databases, catalogs, ...whatever could be added to the sidebar as quick references. Imagine librarians producing short videos entitled, "How to find a book on the shelf at GENERIC Library." What fun, and oh the possibilities! I'm such a nerd.
