Tweet, Tweet: A Crash Course in Twitter for Nonprofits

4. Direct message or "e-mail" posts
Pro: Facilitates a private, more personal conversation between two users.

Con: No cons, in Haydon's opinion. "I'm a big believer in one-on-one communication," he said, adding that more than 70 percent of his posts are via direct message.

"At some point, you want to kind of get away from direct message and then go to a phone call, e-mail, those types of situations," Haydon advised. "So, you definitely don't want to maintain a 10-year relationship on Twitter. In fact, it's going to develop into something else."
