Attention geek speak following:

Just implemented PubSubHubbub on this blog using a very easy guide (PubSubHubbub + WordPress + Feedburner + FriendFeed = Realtime Awesomeness). In the process I moved my RSS feed to FeedBurner, so now you can read the whole posts directly in the feed (incl. pictures and videos). What PubSubHubbub essentially does, is push updates of my blog in realtime to services subscribed to the feed (for example FriendFeed). This means you can now see a new post from my feed in near realtime appearing in my FriendFeed stream and Google Reader.
