Youtube's filtering technology may be causing advertisements to appear on content without permission.  Besides the possible contract violations, the ads create catch 22's when uploading openly licensed (ie. Creative Commons) content to Youtube.   Youtube could have a significant effect on the future openly licensed video content.  This is appears to be a slap in the face to open content and step in the wrong direction.

Trademark holders are rushing to protect their marks on Facebook as a result of the new "username" feature.  Facebook recently granted all registered users the right to create personalized usernames in the form of URLs (www.facebook.com/username) because it expedites the search process for individuals and businesses.  With the creation of the username, you can now be linked directly to the profile you are looking for instead of wasting time scanning thousands of search results. While it seems the username is a helpful tool, many trademark holders are worried that cybersquatters will jump on this opportunity to wrongfully register their marks. How will the new Facebook policy towards markholders affect legitimate free speech.
