AARP' older wiser wired initiative

AARP’s Older Wiser Wired initiative is a great source of presentations about the 50-plus and the Web.

I would recommend looking at designing Web sites for older adults.

This is an “Expert Review” of 50 Web Sites that applies: "heuristics through a new model of older adult use of the Web". The model is applied to 50 web sites that are likely to be used by an older adult in the normal course of their day and reveals ways that sites could do better to increase their usability for everyone.
