My original source for current news about Iran was "The Lede" of the New York Times. It was a good aggregator of news, pictures, and videos from various sources, but the flow seems to have slowed considerably have things have "quieted down". It sometimes is hard to find the latest page. The link in an article may be to the previous day or there may not even be a lead article on Iran. Also, the Times doesn't have the same reporters aggregating for The Lede everyday.
I have now added The Huffington Post to my list of periodic checks. Nico Pitney's "Iran Uprising Live-Blogging" has had many interesting items, including one of the British hosts of Iran's PressTV quitting. For a few more details see, the 5:16ET item in the 2009-06-30 blog.
