I was just posting a reply when I had to stop and wonder what pronoun to use for a chowhounder. This happens quite a bit, especially when the username doesn't give any indications.
I think it would be useful to have some kind of feature that tells you whether you should be saying "he" or "she".
Though it can change how one interacts with another (yes, in an ideal world, it shouldn't); I see this happening anyway when someone's assumed the gender of another poster (sometimes incorrectly, which raises interesting ponderments - but that's another topic).
If you had the option, would you indicate your gender so that others know how to address you, or would you prefer to keep them guessing? If the latter, I'm curious to know why? (Just because I'm in a pondering mood)
