My rule for social media is the following:  only go when you know exactly what you&#x27;re looking for.<p>The academic community on twitter is very active and the content is very good, so I go to twitter to keep up with the latest cogneuro trends.  This having been said, I&#x27;m now clearly in a professional environment, so I think about what I&#x27;m writing.<p>I walk through twitter in the same way I walk through the ghetto:  mouth shut and head on a swivel.  I&#x27;m not going to start disseminating my political opinions as if the average twit gave a damn.
