I have been using FriendFeed for a few days and I have been really impressed:
a) It is super easy to use (specially if you start using it by adding the facebook application because it will automatically discover and add all your friends).
b) It has a very simple user interface.
c) The ability to comment/have a conversation around the items makes for a more connected experience.
d) I also like how like twitter, everyone’s friendfeed is different despite the fact that they are based on the same slices/they all intersect.
I think that the end result is that I have less incentive to go to facebook when I want to determine what my friends are up to.
We are going to have to think about if and how feeddo can integrate with friendfeed.
Also, Cyril has been working for a few months on a new project called Yokway which has elements of friendfeed in it. Looking forward to Yokway getting launched in the next couple of weeks. (Updated: Louis Gray has a review of Yokway – based on the pre-launch UI)
