Una de ellas sería friendfeed (mi friendfeed) que nos permite llevar un resumen de esa 'vida digital' sin necesidad de vivir dentro de la aplicación (como sucedía con Facebook).
Por lo demás, interesante el punto de vista de Dare Obasanjo en No Contest: FriendFeed vs. The Facebook News Feed
The thing about the way FriendFeed works is that there is little chance that stuff in the feed would be considered spammy because the content in the feed will always correspond to a somewhat relevant user action (Digging a story, adding a movie to a Netflix queue, uploading photos to Flickr, etc).
Y Charles Hudson, en FriendFeed and the Facebook News Feed - FriendFeed is For Sharing and Facebook Used to be About my Friends.
In the beginning, the Facebook News Feed was really interesting. It was all information about my friend and what they were doing. Over time, it's become a lot less interesting. Right now it feels like my Facebook News Feed is trying to do too much - it's trying to tell me what my friends are doing, what applications they're installing, what those applications are doing, advertise products that I might find interesting, show me photos, and do god knows what else in the future. Simply put, the Facebook News Feed is losing utility to me because it's trying to do too much. Adding in interesting or cool things that my friends are finding or doing on the web will just make that problem worse.
