So Facebook is pretty good at finding people you knew from a zillion years ago. I’ll give it that. Man – the friends from elementary school, the random people you drank with in high-school down by the locks, it’s an endless stream of slurred memories and fun times. Seems half of the population of the Laurentians (north of Montréal) LOVE Facebook and can’t get enough!!
An interesting thing is that Wikipedia says that FB is the number one photo website on the internet (ahead of flickr). I guess photos with heavy context is appealing (groups/tags/friends).
They also have a VERY well done mobile site which is blazingly fast. Actually – I find the whole Facebook site to be one of the fastest sites on the net. Wonder about the PHP and SQL behind it all. Must be some heavy caching going down.
