Wakoopa tracks the software you're using, and tells the whole world! You can also find out (at their site) what new versions are available of the software you're using, and read reviews of things you've got, providing other people have got them too. Which is not the case with some of my stuff.
I'm so avant garde.
You can also click through to the developer's own site, if you want to find out more. So check out the GIMP, Rainlendar and Ditto, all more or less useful, especially Rainlendar which I love. I'm still on a steep GIMP learning curve, and Ditto has never been used, but one day it will save my life.
Aren't the Intertubes wonderful?
