After wrestling with Facebook Connect for a while, we've decided to wait and see how their policies evolve. According to #8 at the
FBC Policy Page, we can't post to your Facebook News Feed without popping up a window for you here every time you fuel-up so you can approve the feed item. That seems ridiculous and clumsy for everyone involved. The one ray of hope is that the page says, "This process is still being finalized. For now, you may not publish one line stories automatically." So this policy could change and we'd be back in business.
Until then, you can try out GrantHenninger's Twitterfeed hack, or import your Fuel-up Feed to your Facebook notes. I explained how to do that in the last comment
in this thread. That works fairly well too.
