I wrote the other day about what I saw as the problems with social news web sites and my proposed alternative. That alternative, the Facebook application called Wildfire has now launched.
Based on feedback from users a couple of changes have been made:
1. The standard page you see is a random selection of stories, you can pick any of these and forward them to your friends and display them in your profile.
2. Wildfire will now pull down RSS feeds you specify and build your "My Fires" list so that you can choose to forward some or all of the stories from RSS. RSS feeds are pulled down twice a day.
