If your dad is anything like mine, he`ll definitely get interested with it, in his own time. When my parents first got the internet (they were on dialup), neither of them were too interested. My mom still doesn`t use it a lot but I think my dad is on it everyday. I told him about Skype and he just went crazy with it - calling everyone and saying "hey, guess what! I am talking to you on the comptuer!"
He is so funny - gotta love him.
When my dad started getting interested in stuff, I helped him out by bookmarking some pages I thought would interest him. It certainly worked well... he has tons of pages in his bookmarks now.
I`m one of those people who can barely remember what life was like without computers. We got our first computer when I was 13. My mom wanted me to be able to do my homework on it. It had a 14.4 modem in it, which I eventually upgraded to a 36.6 *L* I learned how to use the Mosaic web browser and built my first webpage on geocities, using HTML that had been taught to me by a friend`s dad, when I was about 15 (1995). So I guess I never really had to be sold on it... I`ve been a computer/internet junkie almost all my life.
I`ll admit - I`m completely and hopelessly addicted. I own a dog forum, and visit 2-3 other forums daily. I listen everyday to internet radio talk shows, and internet music stations. Before I got paid to design websites, I designed them anyway, in my free time for fun. I think I need "Internet Addicts Anonymous"
