Haha, uh huh. I agree with most everything you've said. Your identity should totally include more aspects than just: "I am going out with so and so, and s/he did the most amazing/wretched thing two seconds ago."

I haven't had any trouble with people never shutting up about SOs on facebook, luckily. I'd probably block them if they did. One kissing picture every few months, sure, but ten a day? *cough*

That and being a rude ass will get you blocked from my fb.
