Here's a baker's dozen of interesting things. I offer them up in hopes that you'll reciprocate.

In the early days of the Web, proto-bloggers shared links with one another. "Look what I found"! Karma ruled the day. Let's share what we've got, man. Someone on the Well pointed to Yahoo! and we were enthralled. You could go through every link on Yahoo! in few hours but it was the largest link list we'd ever seen.
If you enjoy any of these links, post a link to one of your special places in the Comments section. Share the wealth. Maybe we can start a movement! Make the gift economy a reality!
