After a recent high profile settlement by the FTC against Twitter for security lapses, we expected to see a wave of panic in websites that might have potential security holes or expose "private" postings through the failure to properly handle web crawlers and other mechanisms that peek under the home page.  With all of the hubub about Facebook's privacy settings, it will be interesting to see whether the Twitter settlement is used as a shield in favor of user self protection or a sword to poke holes in Facebook's privacy protections.  Evidently, the FTC felt that Twitter's privacy settings offered user protection that was important enough to warrant a settlement on the issue when those privacy settings were compromised. 

On a side note, it will be interesting to see how Twitter changes 20 years from now when its ban on being "misleading" ends.
