I like what tweetstats does, which is a set of graphs from of your twitter stats.
I also like the little message at the bottom of the page
Here’s my Tweetstats
Zooming in a bit…..
This shows I tweet a lot, but not as much as I used to
This shows that I am pretty consistent but tweet more during the week than during the weekend
This shows I tweet more in the afternoon. For some reason I tweet a lot between 4 and 5 pm.
What does your tweetstat tell you about you?
