It´s surprising how little variation there is today on activity feeds, everybody seems to copy FB.
What I´m trying find is alternative forms of visualisation of activity feeds, ones that use more spread forms than the typical "list" design.
Feeds could use some clustering, e.g. by persons close to you or by topic, something not done by most feed styles today (or at least not visualized).
One of the more noticeable attempts I found so far is Google+ Ripples.
So, what´s the most interesting ways of displaying fullscreen activity feeds besides the well-known FB style you came across?
