Diigo is fantastic, but I wish Diigo could automatically "bookmark" (import rss feeds) my latest shared items from Google Reader, favorite YouTube videos, StumbleUpon items, etc. Then I wouldn't need FriendFeed and I would benefit from being able to tag and share those items just like I can with my regular Diigo bookmarks!

Down the road, it would be cool to have automatic semantic tagging of the bookmarked/imported content like Twine.com.
