Since 2 weeks my new post are not shared on my Facebook page anymore. It is shared on Twitter and LinkedIn but not anymore on Facebook. It worked fine till 2 weeks ago. I have several blogs and all have the same problems.
Note: RSS Grafitti http://www.facebook.com/RSS.Graffiti can be used for posting to Facebook walls if you prefer. RSS Graffiti periodically checks the RSS/Atom feeds that you specify and posts any new entries it finds to the Facebook Walls that you specify. You can get any feed written on any wall (Facebook Profiles, Fan Pages, Groups, Events and Application Profile Pages). In fact, multiple feeds to multiple walls. You choose the combination.
