Here’s a random but fun tool. It may not have a lot of use in the classroom but it’s fun to try anyway. It’s a new tool called Sleeping Time that lets you see when your Twitter friends sleep. It takes the most recent 1000 tweets by a Twitter user .. analyzes them … applies some bit of magic … and then lets you know roughly when they go to bed, wake up, and how long they sleep.

This could be eye-opening for more than just your friends though. It could give you some insight into how YOU sleep. For example, I apparently sleep between 1 a.m. and 8 a.m. Apparently I should be aiming to go to bed a little earlier. 1 a.m. seems a bit late. Or perhaps I use Twitter too late into the night.

About Sleeping Time

A bit more about the service from the site:

Specify the Twitter username of your friend, or even your favorite celebrity, and we will figure out the sleeping pattern of that person. See sample report.

Sleeping Time will fetch the last 1000 tweets of a Twitter user and then determines the approximate sleeping schedule based on the time when he or she is least active on Twitter.

There’s no rocket science involved but lot of people say that the results are pretty accurate. We only index “public” Twitter profiles and will never post anything to Twitter on your behalf.
