Tweets are limited to 140 characters or less. Why do experts feel tweets should be even shorter?

A) Shorter tweets allow the user to send out several tweets in a row to "tell a story".
B) Shorter tweets aid in the ability to retweet the message.
C) Users have a short attention span and won't read a tweet of 100 or more words.
D) Twitter will automatically change links to a length of 22 characters.
E) Shorter tweets allow the use of more visual aids and emoticons.

Answer: B
Explanation: B) The fewer characters you use, the easier it is for your followers to retweet the message, especially if they prefer to use the classic method of retweeting, which is to add "RT" and "@senders-username" to the beginning of a retweeted message. If you leave sufficient space, the users may even add their own blurb or endorsement to your tweet when they retweet it to their followers.
