Alternate Paths: Scratch, Alice and Greenfoot

I was just flitting about the webs myself, and came across this discussion of three recent educational languages.  The age targets are interesting:

I'd say Greenfoot comes closest to my target for my hypothetical audience (mostly 15-25, mostly male).  Greenfoot is a visual programming environment for Java which gives a jump-start to the interesting bits, with what looks like great visual feedback.

I kind of suspect that if you ended up here, you have an interest in programming for production (be that personal, open source, or commercial use).  For that kind of goal a Greenfoot and then Java path wouldn't be so bad.

Check out Alice and Scratch if you feel they better fit your profile.
