I validated the card for my website but still its not working at hackersnewsbulletin.com


Still Twitter Card for summary not working after the approval on website hackersnewsbulletin.com


We are experiencing similar issues with our Twitter Card (https://twitter.com/PaperShare). The papershare.com domain has been approved in the Twitter Card Validator; however, the tweets for URLs (like http://www.papershare.com/paper/live-from-oow-whats-hot-at-the-show--intel-chip-chat-episode-222) do not currently appear as twitter cards.
