You can add the sites you want to share updates from, much like FriendFeed.

You can control who sees updates in the manage my updates link at the top of the section. If youve already closed the Share Sharing Updates From Other Websites module, you can still add other websites by clicking Share More, the Yahoo Profiles Team points out.It is interesting to see how Yahoo is evolving into a more social networklike entity. I would be surprised if Google Profiles didnt eventually start including a similar feature to my updates.
