Perhaps there is some temporary disappointment that the presentation is a poster session and not a more prestigous live presentation in front of the general assembly. When I go to scientific meetings the poster sessions generally have less impact and buzz. Funny though the truth is many times the presentation type is more the result of grouping similar topics from various labs together in a convenient format rather than just on scientific merit alone. Ultimately the data will stand on its own merits despite the presentation type...which is why I am long ....
