It is mainstream that to share a news on Twitter one should repeat it a few times, for the simple reason that your followers aren't up online on twitter all day and that they are likely to miss your great news.
At Wisemetrics we like to look a statistics from lots of data points, and since we have our hand on around 1B tweets, we thought we could get some concrete numbers about if one should repeat tweets.
