Like Ankari, I've recently set up a Twitter account in order to spread the word of my writing. I've already got a few followers, including this website! My techniqure is to tweets on pages which I think will be accessed by the right people. I usually provide a link to the blog where I post my work. I assume (hopefully correctly) that people will become followers if they like what they see. Those who know Twitter well, can you say if I'm going about things the right way and if there's any other ways I can make use of Twitter.
