If you are using social networks, you are also creating favorites. On Facebook you 'like', on Twitter and Google Reader you 'star', on Delicious and Pinboard you 'bookmark' and so on.
Find Favorites. Instead of spreading your favorites across different networks, use Favs to sync them to your Mac. Don't waste any more time on searching for your favorite content - Favs has a powerful search feature build right into the application that makes finding what you like a breeze.
