I think there is a definite need for sites for the older generation. However at the same time there is a need for education of some of the common things that we take for granted over the web.
A few examples:

If i gave my father a URL to go see, he will type it into the Google search box, not the address bar. Then click on it once found in the search results.
Messenger is seen as a form of email, not instant communication.

I don’t use these examples to jest, …

Just been to the qantas.com website to have a look at travel dates for April. Normally I would say ‘i have to travel on the exact date’ however in this case I looked at the ‘flexible with dates’ option.
The interface that was returned presented a matrix of the departure and return dates, with all the prices on one small table. Excellent! So i can look at the prices (all the same in this case) and then pick a combination of departure and return dates with one click.
Well …
