You may noticed Feedburner’s Feedsmith plugin does not work with the latest WordPress 2.9.

Some says that Google is behind the inactivity of the Feedsmith plugin as WordPress seems to be a direct competitor with Google’s Blogspot service.

If you need some moo-power from Feedburner, just install an alternative plugin named FD Feedburner by John Watson.

Update: Your wordpress feed will be redirected to Feedburner only after you make a new post :)
