This is the second time that Jeff Atwood's heavy handed approach has cost Math.SE a generous helpful member who is also a well respected professional mathematician. The first incident occurred in November.

In both cases, if he had expressed his concerns to the moderators, and let them address his concerns, I am confident the issues would have been resolved amicably. As it stands, there are a lot of angry people, including the moderators at Math.SE.
