Only two out of seven went off. We can probably rule out al-Qaeda. They are pros. If they had planted seven, all seven would have gone off.
There almost certainly weren't 7 bombs - the Daily Mail was just parroting a Wall Street Journal report that turned out to be probably untrue.
"Counterterrorism officials found five additional suspect devices around the Boston area on Monday, but a law-enforcement official later said closer examinations led them to doubt that they were bombs. An earlier version of this article cited people briefed on the investigation saying officials believed they were undetonated explosive devices."
Not really. Some are pros, some are just silly sods being funneled into AQ’s “lone wolf program”, usually given a bit of online training, or hands-on training at almost any mosque.

Like the shoe bomber?
We can rule in the al-Qaeda. Both bombs went off perfectly. Contrary to other reports, the official word is there were no other bombs found.
