Are you sick of going to a social networking site and having some 14 year old (that you could conceivably be the parent/grandparent of) telling you, "You have no idea how the world works!"?
Enter Eons.Com. "A social networking site for Boomers". While it is "grown up" it is not "adult", at least from what I've seen.
Great user interface, very easy to use and upload images, videos, etc.
A profile page that actually LOOKS like a profile page (as some sites are sorely lacking in that regard).
Seems most of the activity occurs within "groups" (based on your interests) but you do have private email. Seems like this might be a good one.
As it stands now, I recommend it. (Cool rating instead of Heart, due to no chat room)_______________UPDATE_____________
Site is now dead but trying to make a comeback.
