Of the major social media platforms, Twitter is, in my opinion, the most effective for wordsmiths like textbook and academic authors. The 140-character constraint on tweets—the messages one posts on Twitter—turns out to be rather freeing: the site rewards concision and encourages straightforwardness.
Specialists like textbook and academic authors can and should use Twitter for professional marketing purposes—to demonstrate their know-how, interface with other experts, reach readers, generate leads, generate publicity for their work, and make professional connections. All of these aims can be furthered with Twitter—it’s just a matter of tweeting intentionally.
