Cool story:  I just got out of a meeting with a VC who is a potential investor in OpenLogic.  At one point during the meeting, he asked about adoption of open source application frameworks — specifically Struts and Spring.  I pulled up the web site for The Open Source Census, went to the All Packages by Name report and found out that Spring had been found on 8% of the machines scanned so far and Struts on 16%.  The VC's mouth dropped open.  He started staring at the screen and writing all sorts of numbers down in his notebook.

This is the promise of The Open Source Census.  I know we've got a ways to go to collect more data, but the data makes people salivate.  And it's only going to get better.  Now that is cool.
