Facebook is the one app that doesn't seem to integrate well, and it's all the little things. Like uploading a picture, half the time I want to tag somebody the screen bonks out, and nearly 98% of the photos I load I tag my wife in (even if she's not in the actual picture. The other day I tagged her as a mop.), and yet when I type in her name I always get my 10 friends with the same first name before she pops up. No intelligence is applied.
