Update: March 24, 2013
The saga of Adria Richards, who tweeted a photo of men who made apparently distasteful remarks ("big dongles") she heard at a developers' PyCon conference, was fired by SendGrid. One of the men was fired by PlayHaven. But some attorneys say that employment law will work in her favor, as in this story in the San Jose Mercury News here. Was Richards' tweet made in "public mode"?
There is a similar report on Venture Beat, here.
