the future of blogs as a tool for international peace?

We all saw President Obama, as he visted Egypt and attempted to make peace with a country that over 80% have an unfavorable image on America. I didn't watch the speach, I just know that he quoted the Qu'aran (smart move) in its efforts to find a common ground with those in Egypt, considering it is the most religious country in the world. My question is, will there be a time that Presidential candidates don't visit other countries, but simply write a blog about them? Instead of visiting Egypt, will future Presidents write a page or two, and that will be shown all over the news in other countries? I know there is some sort of technological divide, but is there potential for this, at least with developed countries in the future? Instead of meeting with international leaders, will the all just get on AIM and have a chat like we did in class? Will President Obama plead with Omar al-Bashir over skype rather than in person? I think the potential for these ideas is there. If countries can get past technological divide, then its do able. Heck, Osama Bin-Laden already as the art of videotaping down.
