I started to use http://m.facebook.com/ in a moment of idleness today, and was quickly connected to a link (off a friends page) of great interest. The view from http://m.facebook.com/ is the Facebook of a year or two ago, and has all that is required to connect, and no more. I have lost contact with at least one aspect of the my friends' Facebook activity modes with the current interface (at http://www.facebook.com/).
Progress? Not really, just plain feature bloat.
