Here are some of those tweets:

clickmomukhamo: OMG! Major developments in Iran yet CNN isn’t breaking into Larry King who’s interviewing some bikers! #cnnfail

lifeonqueen: CNN is screwing the pooch on this one - top story on web is Six Flags bankruptcy not Iran. Way to miss history CNN #CNNfail

geoffeighinger: RT @Elektracutie They should quit the news and just do travel brochures. #cnnfail

ivanlasso: RT @dabloguiman: COVER IRAN NOW!!!! @CNN @CNNbrk @CNNWORLD #iranelection #CNNFAIL pls RT

Many American Twitter users praised British and other international news outlets for covering the Iranian election aftermath of riots and civil unrest. The "#cnnfail" tag was the third most tweeted topic on the microblogging network Saturday night. The "#iremember" tag and "#Iranelections" tags were first and second respectively.

Throughout the day users on Twitter and Facebook posted updates on civil unrest and police violence going on in Tehran. They shot photos with their cell phones and posted them online where American Twitter users could see them and distribute them.

The Iran government filtered and blocked Facebook and YouTube accounts to stop people from getting the word out on what was happening on the ground. NEWS JUNKIE, The Atlantic Online, and the Daily Kos were the top three online blogs disseminating news on Iran, including the house arrest of Iran’s reform part, Mir Hossein Mousavi. Iranians were also using Tehranbureau to let the outside world know what was happening.

Twitterers were quick on re-tweeting news on Iran and covering what CNN wasn’t. Some of the top stories from CNN today were on Six Flags’ bankruptcy filing, a grandmother in Nevada who was running a meth lab, and the complaints from people about their analog TV disappearing.

Twitter is the second most popular social network in the US after Facebook.
