I saw this video about social networking and online privacy from an event of the Plymouth University. It shows people what they should put online and what they need to be aware of. Have a look at “EFF’s Top 12 Ways to Protect Your Online Privacy” written by Stanton McCandlish in 2002 and “Fact Sheet 18: Online Privacy: Using the Internet Safely” from Privacy Rights Clearinghouse.
Then I found “EPIC Online Guide to Practical Privacy Tools” provided by Electronic Privacy Information Center. Will try some tools on the list, especially the Disk Encryption.
This video was made by Viewbix, a tool which supports videos hosted on YouTube, Facebook and Vimeo. It’s free and easy to use. It seems much better than LinkedTube which is a Flash widget that adds link and sharing options to YouTube videos.
