As a child of the 80's I'd also recommend you introduce him to Mr. Wizard and give him the fun side of it as well which I believe increases interest in the subject nicely. While he passed away, you are still able to order the shows from his website. http://www.mrwizardstudios.com/
Okay, I understand why they did it but what a wasted opportunity. Why not quietly add a hidden pixel on the website and semi secretly track all the ip's and timestamps of visitors to their site. Lots of information to glean from that....
Why not just have a simple white list requiring you to approve every website (temp/perm/block) that attempts to open? Yeah its annoying but its less annoying than pop up spam.
I guess they played too much FFXI and decided to make real Mithra to play with, lol.
