Fascinating. According to this article by Dan Macsai, Hubspot’s viral marketing scientist Dan Zarrella “spent nine months analyzing roughly 5 million tweets and 40 million retweets” to formulate “The Science of Retweeting.”

There is a lot of interesting information that I’ve been curious about in Dan’s analysis. I especially like the Time of Day graph - good stuff. The afternoon tends to work better for me too, and I can honestly say that I’ve personally contributed to the Friday, 4pm spike. Who doesn’t like to do a little tweeting before the weekend?

To top off the sweet analysis, from the little interaction I’ve had with Dan, he seems like a really nice guy. Dan also (apparently) has a book coming out called The Social Media Marketing Book.
