This occurs for hours and hours throughout the day on both an Infocast 8" and a Chumby One, primarily since the series of server crashes at chumby.com at the turn of the year 2011-12.  I understand there was a problem also with Twitter...which seems to be cured...but now Facebook is "in the barrel".

Also, the friends who post in FB on the Chumby aren't sometimes the same ones that post on the website...is there something old and stale about the API which the Chumby app uses to get at the FB stream which is ignoring your current friend's list settings and letting the junk you once turned off come through?
