I think half the people I know make fun of me for not using Twitter. The other half make fun of me for using Facebook. The sets are mutually exclusive.
I am not alone in my failure to “get” Twitter. In the brief time I’ve observed it, this is my favorite “tweet”:
Twitter seems more about allowing large groups of people to observe your navel with minimal effort.
Word.
(Do people still say that?)
I make fun of you for having a Facebook page. And I still say “Word.”
