This was really bugging me!
Youtube has “share on facebook” button, but it would only post on my profile but NOT on the homepage which means nobody ever sees my links but me…..ie POINTLESS!
Here is a screenshot showing the checkbox which needs to be ticked to share youtube videos on facebook
“Publish to Streams” MUST be ticked to work.
Thanks to Teresa Brusuelas Coburn on the facebook forums for posting the solution http://www.facebook.com/topic.php?uid=2309869772&topic=9131&post=52259
