Maybe his initials are K. T. D.
That has a higher prior (because I imagine more people have those initials than the last name Tydee) but lower likelihood ratio- I think that the combination of "K T" would call to mind the female name "Katie", the use of "ty", an abnormal way to write the pronunciation of the letter "T", suggests sounds were on the mind if the name were constructed from KTD.
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?
