Much is being said about how the baby boomers or "silver surfers" are flocking to the Internet and adopting this new technology for communication, banking, researching a variety of topics and socialising.  I think it's fantastic that the older generation aren't being left behind and want to get on board. 

A number of social networking sites specifically for the older generation have developed over the years.  These take into account a cleaner design and layout, larger fonts, less colours and topics specific to an older target market.  A particular example is www.tbd.com

Online discussion groups and expert groups offer a wonderful way for retired people to connect with the world and to be able to share a lifetime of knowledge and experience with everyone.

Of course there are also online dating web sites for the single retired person and, who knows, you might end up in a successful relationship again!
