Actually, this is a pretty cool. DOS has created a social networking site for J-1 exchange visitor to share their experiences. I was also impressed by the free speech on the site. Take this post from a frustrated visa applicant:

In one of the sides, Department of state talks about the open doors and
secured borders policy, and encourages international students to study
in U.S.

On the other side... when a Stanford summer student like me apply for
the visa at the American embassy in Cairo - I am from Cairo, Egypt, the
American embassy employees insult me and force me to take off my belt at
the embassy's gate, and insulting my family's name, and treating me
like an animal...


The blogs and video posts are also a good idea.
