I've been thinking of working on things with people I'm romantically involved with... what's the experience like? What are the ups and downs?
The Downs: You don't always see eye to eye, and you need to be able to work things out.
The Ups: For me, my wife is not IT oriented, so doesn't try to tell me how to do things, but provides very valuable insight into how a normal user would approach things; her ideas are very good. Another point - You know your partner isn't an idiot:)
