In my view it would cause an average USian to think you are female but that only matters if you care to be mistaken for female. I wouldn't call it deceptive and to me people can choose any nickname they want for whatever reason as long as it's not overly crass/offensive/inane.
Though I'm not sure this warranted its own post, rather than say a comment in an open thread.
The distinction between open-thread comments and discussion posts is mostly a matter of taste; we get a lot of random stuff in discussion.
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?
