Some interesting numbers regarding JSP usage on the Internet. Hint: it's up 94% since last July (2002). Of course, as they mention in the article, they started with some pretty low numbers. The interesting point the article raises is that the operating system underneath JSP is probably not what you would expect:

Linux - 40%
Windows - 26%
Solaris - 17%
Other - 16%

Yikes, Windows is beating out the Solaris operating system despite the WebLogic, WebSphere, etc. power? Interesting indeed. =)
