Gamers and sailors: strong feelings about pirating.

Gamers and wine connoisseurs: lack of fine motor control being bad for business.

Sailors and wine connoisseurs: drunks.

You forgot network admins!

Also most of the other overlaps:

Gamers and
Sailors: constant swearing
Connoisseurs: get told it's not a real job
Admins: bothered by ping issues

Sailors and:
Connoisseurs: always in search for the nearest bar
Admins: Surfing in their free time

Connoisseurs and Admins: explaing stuff to morons who just want to consume

Gamers, Connoisseurs and Admins: their private equipment is top notch as well (and probably in the basement)

Admin, Sailor and Gamer: the unwashed masses

meanwhile network engineering students get mad at trunk ports

Also people who work with ancient industrial equipment that can only be programmed via serial RS232

You know what's not a bad port? Dr. Aroused's Boxed Ruby Port.

I get mad at Windows features occupying ports, even when that feature isn't in use.

I'm in 2 of these circles.

NetBSD users.

Fun fact that may or may not be true: The left side of a ship used to be called "larboard" (to go with starboard) because that's where the larder was - where the food was stored, and this was supposedly changed to port because that's also where the wine was stored and it was both easier to say and easier to identify as being different from starboard.

Another fun unverified nautical fact: The word shit originated as an acronym for the storage of cow manure during transport at sea - Store High In Transit. Dried cow pies apparently have...violent reactions to salt water.

A guy I worked with had a real newspaper headline pinned up above his desk:

Port Asks Serial Levy for Terminal Access

I'm all three. Kinda funny, but I don't drink much port and rarely find a bad one.
