TeacherSource | learning.now . What Exactly is a Blog, Anyway? | PBS:
<blockquote>In the coming weeks and months here at learning.now, you’re going to hear a lot about the exciting educational work that’s being done with technologies like podcasts, photo blogs and video blogs, just to name a few. But before we jump too far ahead, I thought it might be useful to talk about where all of this got started: blogs.
If you don’t know what a blog is, you’re not alone; according to the Pew Internet & American Life Project, nearly two-thirds of Internet users don’t have a good idea of the meaning of “blog.” In case you fall within this group, you’re in luck, though – you’re looking at a blog right now.</blockquote>
This is an interesting primer, but geeze, you think they’d mention the actual history of blogs, such as Rebecca Blood :: Weblogs: A History And Perspective which I think is a great intro/history.
