Top Voted Definition for #t_at_
(please see alternate one "_" ... I am considering to delete this one) #t_at_city may be used to get people to tweet from a virtual place. For example, at a given time, x number of people may be found tweeting at #t_at_newyork or #t_at_bogota. Note that the person does not need to be physically present at those places, it is a virtual place to group people that write tweets.
