Blogging, what's it all about?

Blogging has been cropping up alot lately on the internet, it rather confuses me, it's a page where you can keep a journal of some sort about life? or a place to rant?

Why is blogging so popular? what is it all about? this is something on the internet that went so fast I couldn't even follow what it's about.

I suppose I could always read a few and get the picture, but what is blogging all about? why do you blog?

thanks

dude blogs been around a hella long time

we even got ATS blogs, you can click mine in my sig


really to me it's just like having an interactive webpage where you can post whatever thoughtful or asinine thing you can think of and then if someone agrees or disagrees or just wants to say sup yo
they can :p
