Facebook obviously hasn't heard of the phrase; "If it ain't broke, don't fix it". Despite reaching 500 million users (with a rumoured 600 million now signed up) Zuck and the gang love a tweak. We think they get bored.
The latest change involves Facebook Pages. Page owners will now be able to carry out actions on behalf of the page - after logging in they'll be able to add comments, like and all the other gubbins that makes Facebook what it is.
Pages will also take a leaf out of the new profile pages with the most recent experiences and pics at the top of the page and the “Everyone” filter on the wall will let you show people the most interesting posts first.
There's also a new area for people to discover mutual friends and interests and, this one is more for developers than general users; iframe tabs have now been enabled.
