"Variety: You know that guy on the street that hands you a flyer that you toss into the trash 5 minutes later? Never become that person! In addition to insider info on our programming, I update the feed with animal news, photography, songs and we even have the occasional giveaway so that our followers don't feel spammed or inundated with tune-in reminders.

KISS (Keep it shorter silly!): Just because twitter allows you 140 characters doesn't mean you have to use them. Try to keep your tweets as short as possible so that they are both easy on the eyes & RT friendly."... Animal Planet
