whouses is a simple script that scrapes data from geek interview site usesthis.com to find out what geeks are using what hardware/software/tools.

It's pretty simple in design, and the results need to be given some allowance for inaccuracies (i.e., an interviewee mentioning a product, but not actually using it).
I whipped this together in an hour, but hopefully can work on improving the algorithm to be more intelligent.

Just so you don't have to do it, 97% of the geeks interviewed use a Mac :)

To use 

./whouses <tool>

i.e., ./whouses Mac
