Actually, Maemo News has a feature for adding your Attention Profile into the calculations. This way the system takes into account the things you've favourited in the past, plus your delicious bookmarks if you use that.

Currently the system isn't being used, but at least if your maemo.org account is old enough you can see what attention data it has gathered for you on the site.

If enough people find the idea of "personalized" Maemo News useful, we could start testing it with some group of people.
