A recent study on the social life of a tweet finds that the vast majority of tweets receive no response whatsoever and the lack of a response implies the tweet "has [not] resonated enough with someone that it sparks a conversation or encourages someone to share it with their followers."  While these numbers and the research behind them are useful, the conclusion merits further exploration for a couple reasons:

1. Compared to display ads whose click through rate in the U.S. and Europe hovers around or below 10%, a 29% interaction rate is extraordinary.  Moreover, the effectiveness of a tweet can't be measured solely through responses because a response may not be requested, required or even useful.
2. Research focusing on social marketing on twitter suggests it is not how many people you reach with your message but who.  In the context of twitter—where most users are completely passive—the research suggests that responses from influential users are where the real value in social marketing lies, rather than massive numbers of users with inconsequential networks.

If u can fnd another $0 advrtsng mdm w a  29% response r8 in <140 chrctrs, do it.  Othrwse, Twtr looks like one of the bst optns avlble.
