The Recommendations Bar seems to work well, but there is not an ability to remove the most recent read action from a user's timeline. As all of the actions are handled by the plugin, there doesn't seem to be a way to get the ACTION_ID generated by the Read.
As such, Facebook will not approve my Read Action with the Recommendation Bar because I can't provide a link in the article that says "Remove from Timeline" that deletes the action from a user's timeline.
And just as an update, the "social reading" function of the Recommendation Bar has been removed, probably due to the Read action issues (which were reported as a bug several months ago and marked as fixed at the same time as the feature disappeared). It just replicates the Recommend Box functionality now. –
