On the face of it, Twitter would not seem a particularly good vehicle for promoting photography. As you likely know, Twitter is a text-based system in which individual communications are limited to 140 characters. Many people use Twitter as a kind of blogging tool for the attention deficit generation—although, of course, Twitter is used for serious communication purposes as well. It’s reasonable to assume that there’s more than meets the eye when the United States government uses Twitter to promulgate important news, and when revolutionaries active in the Middle Eastern Renaissance use Twitter to communicate. Still, none of this stuff is visual—at best it is links to visual material such as your photos.
