facebook is stalking

I'm on the facebook. I don't really update it and whatnot. I become friends with people and that's about as far as it goes excepting the very irregular graffiti scrawl. I guess I don't "get" it. I really don't get why it tells me every little thing that every one of my friends has done across all of facebook - even when it has absolutely 0 to do with me. It's ok. I don't need to know when my friend updated their update dealie.

What is the motivation here? Is this supposed to horn in on Twitter's market? Twitter is another thing I don't really understand. Take my average post divided by 100 more boring times 80 times a day . . . ? Is this good for anyone?

I guess I'm just old-fashioned.
