One article notes the narrow base of the recent protests in Tehran:
Thursday's marches were largely inspired by young activists and students using the Internet to get the word out. They were able to make a startlingly strong showing with such informal methods — but doing so consistently at a time when activists are being arrested may prove difficult.
The protests that erupted in the weeks immediately following the election were far larger, with hundreds of thousands from all levels of society filling Tehran's broad avenues.
As long as the narrow base of protests keep coming out, there is always the chance that they could spark renewed and bigger anger that fills many cities with ordinary citizens not Twittering and blogging. And fissures within the mullah elites could make that level of protests lethal to the regime.
But for now, it is a protest movement of the usual suspects on campuses and online.
