Over the last year or so I have become addicted to data visualization and mashup tools. Every day it seems like there's a new one to explore. My current favorite remains PageAddict. Using the Firefox plug-in I have been able to reduce my time on social networks and increase my use of productivity apps. Now I have a new one that's equally revealing.
Twitter Charts is a Yahoo Pipes/Google Charts mashup that takes a user's tweets and plots them on timeline by day of the week and by hour. It's a great way to see just how active a user is on Twitter and when. In addition, it also gives you a sense for how engaged an individual user is in the conversation by revealing the portion of tweets that are replies.
To give you a sense for the differences between Twitter users below are two graphs. The first plots my tweets. The second graphs my friend Robert Scoble's tweets. As you can see there's quite a difference in how we use Twitter. Additional information on Twitter Charts can be found here. (Via Twitterholics)
