Statistics about your Twitter!
If you are a Twitter addict or fan, you will most probably get surprised once you use this great and fun tool: Twitter Charts. You are asked to enter your Twitter ID (which must be publicly available) and then, the system generates lots of charts providing information about your tweets by month, day of the week and hour. It also specifies who you have been twitting with. A nice toy to play with and realise how much time we spend in front of the computer without realising it.
NOTE: Emapey has written a good post about this in his blog : Online Sapiens
