I've been deeply resistant to using Twitter. First of all, to be embarrassingly honest, I'm not all that social of a person and the idea of maintaining such a social site exhausts me (I'm also easily exhausted!). Second, my inner demon is rather convincing when it tells me I have nothing interesting to 'tweet' (is that the right usage?). That being said, I am forced to acknowledge that Twitter is a valuable tool for networking and that if I'm serious about being an author, Twitter can only help me accomplish that goal. Sigh. So, Twitter, here I am! Follow me! ;)
The whole issue illuminates an interesting duality to writing. In my mind, writing is an art. Marketing/networking is a business. I am no business mogul. However, to be a writer, I must become one. It's an old-world (extinct) sensibility crashing into a modern world reality. It becomes very clear that one's success lies with oneself. This is both empowering and terrifying. Hmph, time to grow up, eh?
