A blog-defining a generation

I've been asked to define what a weblog is, which seems somewhat impossible to describe.  Not because I can't, exactly, but mostly because it is so vague of a word.  I guess in one way it is a way for people to express how they feel about things, because nothing can get more personal than writing entries each day to mostly yourself.  If you think about it, sites like Blogger don't mention how many people look at a blog each day, so unless someone you know actually talks to you about it, or if a random anonymous stranger decides to leave a comment, you have no feedback on what you're saying.  You can write whatever you want to, guaranteed to be part of an immense network out there in the internet.  

Another use I've noticed for blogs, not that this pertains to me, is that celebrities (authors, singers, actors, etc.) get to give their fans glimpses of their glamorous lives.  Stars who are idolized every day get to reach out and show the world that they are like every person out there (even though that is a really far fetched theory). 

 I, however, really like reading authors' personal blogs, such as Meg Cabot's (http://www.megcabot.com/diary/), or nerdy movie blogs, such as http://www.denofgeek.com/movies/archive/ (I'm not sure this can be counted as a blog however, but I will count it anyway).  If you have ever watched The Office, the woman who plays Kelly Kapoor writes a pretty funny blog about purchases she has made.  She hasn't updated since April, however, so I get the feeling she is discontinuing that.  I honestly feel that blogs today are purely a new style of expressing ourselves.
