Blogging?

Ok, so would someone mind explaining what the hell a blog is used for? I mean is it just here so we can spiel some crap about our lives and let people stalk us to their hearts content? Are there even any stalker, does any one read this stuff, or had everyone become so lazy that they've switched to youtube? Fuckin' slackers! Don't get me wrong, youtube is great and I have my personal favourites on it, but it's just such an easy way out of having to make our brains actually do something. Perhaps I should keep these blogs short and sweet. Don't want to make you work too hard now do I?
