Amusing video, the photo problem could be worrying, but I haven't suffered from it yet! What does really annoy me is the incessent application invites, which facebook is starting to sort having opened up their platform in the first place.
There's an interesting video on the bbc about a possible flaw in facebook http://news.bbc.co.uk/1/hi/technology/7376738.stm
as well as possible identity theft which was brought to light a few weeks ago, just from details on your profile page.
(sorry if that's been posted before but I thought it was relevant so put it here)
