Summify is a service that creates a periodic summary of the most relevant news stories from your social networks, and delivers it by email, web or iPhone.
Summify distills your social feeds, boiling it down into a summary of the top five or ten most important and relevant stories.
I have been using the service for a few weeks now. The reduced number of items is nice, but I am not sure that I am ready to stop watching the individual feeds.
Give it a try. Let me know what you think.
