What do you mean by Snowden's post? He didn't make a post. He handed over classified material to journalists, who made decisions about what was in the public interest to publish in their newspapers.

Maybe in the years since he's written a blog or an article in the news (he's given a number of speeches or attended events), but that wasn't how he blew the whistle to the public on the fact that the NSA was wiretapping the entire Internet, including the communication of ordinary Americans.
