Bikes and musical instruments are fairly mainstream obsessions. Do you know that there are forums where guys talk about their 15 vacuum cleaners and how their wife is gonna divorce them if they smuggle in another.

Wristwatches are the same deal. Few years back, I wanted to buy a fancy watch, ended up looking at some watch forums. Those guys have an acronym "WIS", meaning "watch idiot savant", that really cracked me up.
