Wakoopa.com is this innovative service which tracks which software applications you are using. Also tells you about the applications getting used by other people who are using this Wakoopa tracking utility.User Interface  as well as the usability rock big time. Seamless is the word which I need to use here. You have widgets about the software being used by you. Small things like giving each person a tag like enthusiast or fanatic work big time. You get a very nice idea what stuff people are using and how twitter has grown.A nice idea about what you are yourself addicted to.Overall a thumbs up from me for the application. Each one of us can give this a try.
