I am curious on how www.gigaom.com is able to callout the summary data of their articles. In addition I am trying to figure out how the summary autoposts when you select the tweet this button and the author's twitter gets tweeted as well.
I suspect the latter is available via twitter cards, but how can I get the summary data to show before the post content. A custom field? Micro-data?
Here are two examples of what I am talking about...
Any feedback is appreciated.
