It ended up with around 6000 unidentified faces here. A large proportion it should know though so its taking forever to slowly go through and identify.

I've got a few photos of very large crowds (approaching 1000) which are all looking up at the camera. It really doesn't like those! It slowed to a crawl and took an hour to process.

One of my friends must have a very generic looking face as it seems to suggest him for nearly everybody!
