This means either cutting your friends out of your private data, selecting your friends based on their computer savvy, or being as vulnerable as the most insecure of them.
I say again: Facebook is the devil. It's a brilliant platform that should continue to grow for years. It uses your own friends to make you do things you would not normally do (like join). As a platform it has no other goal than total domination of the net.
Only a matter of time before that gets clickjacked though.
Most don't understand this. It's a royal pain. Read through this article by PJF, "Facebook privacy - Instant personalisation and connections" ~ http://pjf.id.au/blog/?position=604
Correct me if I'm wrong.
Mouse-over the big freaking div, click on the little cross on its top right, and choose "Hide FarmVille" or "Hide Mafia Wars" or "Hide Doomaflotchie Widget", and you'll never see any updates from the damn thing again. Across computers. Which makes it better than Greasemonkey scripts or browser addons.

Then you can visit any webpage and "like" it.

If you include Open Graph tags on your Web page, your page becomes equivalent to a Facebook page. This means when a user clicks a Like button on your page, a connection is made between your page and the user. Your page will appear in the "Likes and Interests" section of the user's profile, and you have the ability to publish updates to the user. Your page will show up in same places that Facebook pages show up around the site (e.g. search), and you can target ads to people who like your content.
