Social media scientist's 'The Science of Timing' looks at optimum times to tweet

It's a question many social networkers ask: when's the best time to tweet? A weekend morning? A weekday afternoon? 

Dan Zarrella, a self-described "social media scientist" who works for HubSpot, recently hosted a webinar titled "The Science of Timing," which looks at timing in social media and its impact on effectiveness.

ReadWriteWeb neatly rounded up some of the more interesting findings:

• Tweeting later in the day and later in the week results in more retweets.
• The click-through-rate on tweeted links appears to spike in the late morning and then again around 5pm.
• The click-through rate on links tends to decline as more links are tweeted per hour. After about six links per hour, click-throughs essentially drop off.
• Still, tweeting more frequently leads to more followers, but Facebook is a different story: Too many posts on Facebook can more easily alienate people.
• Weekends are an ideal time for sharing on Facebook.
• More people tend to open marketing emails in the early morning than any other time during the day. Weekends also appear to be effective for emails.
