What's the point to Microblog?

I’m not sure I really understand the point of microblog. I don’t think I get the concept or the site.

As I scroll through my timeline, it looks more and more like Facebook but for a niche group of tech-types. Not only that, I see a ton of replies to conversations with zero context so I have no idea what it’s about.

Does anyone actually WRITE on this thing?

I loathe Facebook with a purple passion and I am definitely not a tech type, so is there really any point to being here at all?
