Crafty Business: How to tweet so others will retweet

1)  Don't use all 140 characters.  If you think about it, when you retweet, automatically inserted in the front of the message is "RT @[name]".  So, if you used up 140 characters,
the retweet is now over the limit.  One of two things will happen - either people won't retweet your message, because they are using a program that won't allow for more than 140 characters and shortening your message is not worth the hassle; or your message will most likely be shortened from the end (and that could be your valuable link).

2) Use hash tags (#) and @ to name people and things - that way people who are searching for posts containing that info will see your tweet and people you tweet about will get a message.
