I reported about the reasons behind it here.
Here are some of the pictures that, according to Khamenei's website, citizens have sent of their observations of the trip, and for some a close encounter with the Iranian leader.
Meanwhile, Iran's state news agency, IRNA, is also promoting citizen journalism.
IRNA says each citizen can become an "honorary journalist" for the news agency and send reports about events he or she witnesses to the government-controlled news agency.
IRNA's slogan, "Each citizen, a reporter," is very similar to that used by the Green Movement. Opposition leader Mir Hossein Musavi said in an interview in February that "in the Green Movement, each citizen is a media outlet."
The opposition movement has been facing a news boycott by the state-controlled media and has to rely on bloggers, citizen journalists, and social networks and social media to spread news and information about the movement and its members who have come under pressure from the establishment.
But the citizen journalism the Iranian establishment is promoting is likely to be tightly monitored and subject to censorship in case the content citizens send happens to contain material considered damaging to the government.
