As well as debating whether Iraq is now engaged in a civil war, some of the bloggers writing about yesterday's attacks by Sunni militants in a Shia district of Baghdad are closely watching for the full range of responses of the Shia cleric Moqtada al-Sadr.
Gunmen detonated car bombs in crowded markets in Sadr City and tried to overrun the health ministry, which is run by the cleric's people.
Today in Baghdad, followers of Mr Sadr warned they would suspend their membership in parliament and the cabinet if the prime minister, Nuri al-Maliki, met George Bush in Jordan next week, the Associated Press reports. The Sadr bloc is the backbone of Mr Maliki's political support, and its withdrawal would be a severe blow.
However, some bloggers suspect that Mr Sadr's allies will also respond with violence. After yesterday's blasts Shia gunmen on the streets promised to seek revenge and there were mortar attacks on Sunni areas.
John Robb on Global Guerrillas, writes that the attacks eliminate the legitimacy of the government, because of the failure to provide security. He goes on:
"It is also a deep blow to the legitimacy of Sadr's movement since it didn't provide basic security either. Second, to regain legitimacy and exact revenge, the Mahdi army will go onto the offensive (in contrast to the government). This offensive will likely force them to move beyond abductions and into open action in order to replicate the scale of this attack - this will achieve a goal of the attackers in that it will put these militias in direct confrontation with the US army and the few functional Iraqi army units as they range beyond the borders of Sadr city."
Inevitably, there is also debate about whether the attacks - which claimed more than 200 lives - have pushed the country towards a full-scale civil war. Or whether it is already a de facto civil war.
Hammorabi, writes about the continuous attacks on Shia and warns "the next few days will witness a new kind of revenge".
US blogger Rastaman, writing on Jihadi du Jour, believes the violence amounts to a civil war. "Let this sink in. Our troops are taking sides in a civil war. We are attacking the Sunnis that are attacking the Shia," he writes.
A worrying point in the Telegraph's coverage, and in other reports, is that Shia and Sunni Muslims - who once lived together relatively harmoniously - are increasingly moving into segregated neighbourhoods. This is a process that can only increase sectarian divisions and may take a long time to undo.
Slate's US press review today has a good set of links to the coverage of the bombings in the main papers.
It notes a piece in USA Today saying that on Sunday the Iraq war will have lasted as long as the number of days the United States fought in the second world war: 1,347. There are of course, not many other similarities.
