Spam I am

Spam this morning:

Subject: Greetings, I have learned an interesting thing

What interesting thing have you learned recently?

Spam I am (part II)

Another spam:

Good afternoon, I have a good software

What good software do you have?

And if anybody knows of any good freeware/shareware/cheap software for doing shiny graphs/charts/etc on Mac OS X or Linux, that would be particularly useful right now.
