Form is emptiness, emptiness is form.
While I own an active Facebook account, I don’t “use” as much as other people use it. Heck, its been almost a year since I last scrolled down my feed.
For the interest of those who find it preposterous not to have Facebook always open in a browser tab, here are my reasons why I stopped using Facebook:
Facebook looks at the meta="description" element of the shared link to determine its excerpt. The following link discusses how to do this:

The process requires modifying the header of your current theme, usually the header.php.
It’s also possible that the meta="description" element is missing in your theme (like in CRC‘s Suffusion theme). If that’s the case, just add the missing element.
[EDIT: Ditched this and went with All in One SEO Pack plugin instead.]
