If you're a writer and/or avid reader, Twitter provides a unique opportunity to connect with fellow writer/readers and contest hosts.
Three Twitter users who provide some of my favorite tweets and are incredibly giving writers include Kimberly VanderHorst, Kelly Siskind, and Brenda Drake.
My top three Twitter hastags are #amwriting, #amediting, and #mwsl, where agents and editors list what kinds of manuscripts they're looking for (aka: my wish list).
And my three favorite Twitter writing contests are adpit hosted by Heidi R. Norrod, Pitch Madness hosted by Brenda Drake, and PitchWars, which is also hosted by Brenda Drake.
If you're new to Twitter and have any questions about these links, or how to search for Twitter hashtags, feel free to ask me.
