When the feature debuted, the thrust of the announcement seemed to be that it would populate your local phonebook with contact info and photos from Facebook. Assuming it would quite likely also do the same in reverse, I held off.

And that is what I find most objectionable about Facebook's user experience in general.

Everything I do, every click, I have to weigh: What will this mean for my privacy? Will I accidentally share something I didn't want to? I have to think everything through from Facebook's perspective and try to predict what my actions will be interpreted as consent for the system to do. It's decidedly unpleasant.
