One of the reasons I stopped hanging out in the "atmosphere" (the name for the broader, community driven ecosystem) is that I was personally attacked three times. The last straw was one of the leadership team jumping down my throat because I used the phrase "marketplace of ideas" that apparently triggered this individual.

It's not all pleasant. For me, I have a 3rd time's the charm rule I typically follow. Others may have more or less tolerance for this sort of thing.
