Recommendations Bar not posting 'read' items to timeline

I have seen various posts about the add-to-timeline social plugin being 'broken', however have any of you managed to get the to work?

With the og:type set to article the plugin was marking posts as 'read' but they were not appearing anywhere in the timeline, news-ticker or news feed.

I added prefix="og: http://ogp.me/ns# otilogin: http://ogp.me/ns/apps/otilogin#" to the opening tag, as seen in the HTML examples on the Tutorial.

This did not fix the problem.

Any suggestions or help would be greatly apprecia开发者_C百科ted.
