I've used to do that, not to gain anything, but rather I was curious as to who my neighbors are. So I met this guy at the elevator, whose facebook page I've seen using firesheep. I said to him "So your name is Eduardo, right?" which scared him a little bit, but then I invited him over for a beer and explained everything and showed him how to use VPN to protect his traffic. However, I would rather prefer it to be impossible for anyone to hack your traffic over wifi, because it would make everyone's life easier and safer.
