Arne and Marcus have come up with a killer feature for their excellent iUseThis site: imakeprofile. This nifty new app sends a list of your applications you have installed and compares it to your apps on iUseThis.com. Presenting you with a list of applications you prefer but haven't installed. Great to use when installing applications on another computer or after a reinstall. Currently only for OSX but a beta version of the site targeted at Windows users is coming soon (im still waiting Arne!).
Check out the blog post over at iUseThis.com for more info. If you like it then digg it.
