The nature of Blogging

I've been doing a lot recently talking about blogs and thinking about the nature of blogs. I guess the main message is that blogs should do whatever you want them to. However, it's important that people understand the nature of what blogs are in the main and how they have developed. I find the social nature of blogs isn't always obvious and, therefore, needs highlighting. My reading of other blogs is something that's very important to my learning and is intrinsically linked to this space. the struggle to find/make time to read them. (I currently have over 700 unread posts in my blog subscription). What I probably need to do is cull some of them but that is easier said than done.
