That wouldn't really help your case that J is consistent...

week

Hi Devon

That is a very nice presentation!

Minor details: 

You provide 3 lines of the vocabulary of J on page 2. Why not tell that the
COMPLETE vocabulary is only 41 lines? To me the short language definition is
an important quality of J. 

It is also very nice that J is accessible without charge. 

You do write the word "compact", but not HOW compact. (192 KB). The
compactness contributes to reliability.

Elementary examples makes the audience feel comfortable:
   3+3
6
   3*3
9
   3-3
0
   3%3
1
   3^3
27
   27^%3
3
   
The advanced stuff is impressiv but not comprehensible to non-J'ers.

I miss a negative sign "_" in the Newton iteration "close to zero
difference" e_16.

Good luck!

Bo
