In a few months, there was plenty of time to reflect on the negative points of that post and how they could be taken out of proportion. There is a reason employers frown upon employees making public statements that involve the company they work for - not because they may say something stupid (that would also mean that they hired the wrong person) - but because the media tends to latch onto the smallest details and blow them WAY out of proportion. PR departments exist so that public statements are filtered, watered down, focused and devoid of any potentially negative connotations about the company.
Lesson learned, I guess, and I hope NYU's reputation was not damaged as a result.
