I've seen you elsewhere on this site plenty of times, and I certainly thought you were female. If that's a problem, then you should probably change your username. If not, then keep it.
I wouldn't call it deception (because that implies that you're trying to trick us for some nefarious purpose), but I would certainly call it misleading.
So, my current username often reads as female. This is not intentional, and I am not female. Some on IRC have pointed out that this username could be considered misleading or deceptive. I have no real attachment to it, but I do have a few articles that I've been discussing and planning on posting here, and I think it would be confusing for others if I changed usernames, making it difficult for people to follow the genesis of certain ideas. However, I also don't want to mislead anybody.
Therefore, I pose the question to the community: is my current username deceptive or otherwise misleading, and should I change it?
