Slowly but surely, Friendfeed has been adding features which have made the service a more fully integrated and go-to destination for me multiple times throughout the day to share news and learn what others like me have found interesting, as I can see their Twitter, Digg, Flickr, and Google Reader shared items updates, all at once. Now, with the addition of comments, "Like" capabilities (the equivalent of "Digging") and the ability to share items directly through Friendfeed, the service has expanded to more than just a single repository for date from other services, instead being a platform for new content.
I first became interested in Friendfeed as the service could aggregate friends' Web activity in a single place. But in recent weeks, it's grown to be much more. In October, they added a function to say you like an item or get the feed by e-mail.
Today, Friendfeed introduced a "bookmarklet" that allows me to share Web pages on the service, independent of other Web sites, like Digg or StumbleUpon, directly to those friends who have opted to subscribe to my own feed.
Unlike Digg, Friendfeed isn't open to the unwashed masses, but instead, is open only through invites. Let me know if you want one.
