One of the impromptu perks here is lunch: a most eclectic group of programmers, chemists, physicists, managers, support, etc. congregate around one large table and enjoy a discussion thread that flows thru technology, philosophy, brewing, literature, linguistics, astronomy, cooking, etc. - often all in one sitting. Indeed, if I'm not there I feel I'm missing out. No pressure to join in, but indeed a great perk if you do.
