Crawl the web and you will see that internet skills are key - more jobs using podcasts and live chat meetings, internal corporate websites, Twitter, Facebook, text alerts, and so on. To keep a President for using the tools that even the stoic corporate world is moving to embrace would widen the divide of between the office and the real life of US Citizens.

Facebook is like your brain - while the content may be important, its just a tool and how you use it is what really matters. Believe it or not, some people actually use these tools to do work. Its not like someone is saying "lets get the White House modernized so we can all go play flash games and visit porn sites".
