1. Retweet - This is the best way to gain fans & have readable content. Retweet things from comedians, businesses or anything that relates to your content and brand.
2. 140 Characters - We all know you have only 140 characters to get your point across. Remember to keep it even shorter if you want your fans to retweet it. When someone retweets their name and the originator's name is in the tweet, making it longer. Keep this in mind.
3. Quick Info - A lot of people use twitter for quick information fast. Remember that the more times your fans have to click to a different website, the less likely they are to read your information.
In Conclusion: Keep it Fun & Keep Your Brand in Mind
