How did they know about my Facebook usage habits? Is this a thickly veiled privacy article? Though seriously, it's easy to look back in retrospect and summarize webapps like this. It would have been more interesting if they discussed what the future could hold for Facebook. They are in a bit of a "serves no real purpose" limbo for me and I'm sure many other people. I have some fuzzy ideas on where they can take it to become more engrained in everyday real life, but I don't think society is ready for what I have in mind yet...
