[TriLUG] How young is too young for linux-ish training?

[Paul G. Szabady]

Greetings TriLUGers!

My 7 year-old grandson has been asking me for close to a year to teach 
him to build a website.  Not knowing how to go about teaching someone 
that young, I finally just put up a site for him.  He loved it for about 
a week, then started asking me to show him how to make changes.  I would 
love to begin teaching him some basic html or maybe even some basic 
programming, but I'm stumped.  How and where to begin?  Has anyone ever 
run into this type of issue before?  And/Or does anyone have any 
suggestions on where to begin?  I don't want to push him into something 
that would cause resentment.  On the other hand, he is academically 
gifted in math and reading, loves science and excels in sports.  So he 
already has a track record of pushing himself.  If there's a way to 
"learn" together, I would love to have special papa/grandson time if 
there are any classes that we could attend.

Any/All thoughts are welcome!

Thanks!
Paul
