FriendFeed seems to be heading in the same direction as Twitter in popularity. If you're interested in knowing more about FriendFeed pop over to this post.
I've set up a FriendFeed room for ProductCampToronto. A room is like a mini FriendFeed for a particular subject or group of people. Everyone in your room can share stuff with each other and leave comments that only other people in your room can see. Check it out and join our FriendFeed room.
The core social media tools are in place for networking, communication and collaboration. In the next week I'll be putting together a proposed plan for this event. Stay tuned!
