I think I've figured out my writer's platform "Twitter strategy": follow who's interesting, regardless of who they are and what they tweet about, and have fun. One thing I won't be doing: tweeting every hour on the hour with Yet Another Promo of My Book. That is a one-way ticket to being boring and unfollowed. It seems a lot of writers on Twitter only follow you so you'll follow them, and then it's promo, promo, promo. Like a hall of mirrors, writers tweet "Read my book" at each other, instead of talking to people (some who, hey, you never know, might be readers) about things that make life (and themselves) interesting.
Talk about the writing process. Talk about cool space probes. Talk about a rock star that just died. Talk about your kids, your favorite TV shows, something funny you saw on the way to work, respond to what other people are talking about and make it All About Them.
But a steady beat of alternating one-liner book promos? Is internet navel-gazing.
