[maemo-community] How Social News ranks news items

[From: quim.gil at nokia.com]

Hi, this is very interesting. Please put it in a wiki page not too far from the Karma page. At the end we are talking about karma for people, news, apps... We actually have "karma" for bugs thorugh the Bug Jars and there is a concept for popularity also for the Brainstorm. (perhaps discussion threads one day, we already have the stars).

> * Comments the item has on maemo.org (available only for local news
> items)
> * Diggs
> * delicious bookmarks
> * Links on other blogs (via Technorati)

> Like account or app Karma, the social news algorithm is also easy to
> tweak to include other factors, so the weighting system is constantly
> open for discussion.
