Instead of "digging" stories, or "voting up/down", stories gain credibility only if you deem them worthy of being passed onto your friends.

Randomness means that the Wisdom of Crowds is harnessed without succumbing to mob rule. And RSS integration means you can automatically bring your feeds to Facebook and pass on a subset of the stories. Personally, I started with the Slashdot feed."

The problem with the average is that it hides a savage reality of Facebook applications: some have many users, most have almost none. 86% of applications on Facebook have less than 10,000 users, with 62% having less than 1,000."

My simple and free email image generator service generates a randomized image containing your email adddress. Simply copy and paste the relevant HTML to your web site to get a human-readable image that contains your email address but hides it from web crawlers."
