When it comes to stuff like 'Chairman' or 'postman', as far as I'm concerned that's the name of the job, and it's a lot of yelling over nothing. But sometimes it might be nice to have a gender neutral word. For example:

"When someone wants to cross the road, he should look both ways." We don't really mean 'he'. Of course, we don't really mean 'she' either. In that case, a gender neutral word might be nice so we didn't have to convolute it by saying 'he/she' or 'the person'. We have 'one', but that always sounds a little pompous somehow.
