I just ran across a great blog entry by ConversationAgent Valeri Maltoni and thought it an excellent follow-up to our post this week about the power of the retweet. So if the almighty retweet is the exponential nirvana we're all looking for, what is the content that's most likely to get retweeted? Here Maltoni shares her take, and in turn leads us to Dan Zarrella, the Social Media Scientist, who crunches the retweet metrics, linguistics and etiquette. Zarrella believes retweets "to be one of the most important developments in modern communications, extending far beyond the Twittersphere." (This posting alone is proof of that.) A couple exerpts:

• -  It's okay to ask to be retweeted (in moderation).
• -  70% of retweets include a link.
• -  Do not start the ReTweet with an @ sign, as this will mean that generally only people following both you and the person you’ve @’d will see the ReTweet, defeating its purpose of increased reach.
