I wonder if any parent has ever felt the same way about his/her child - that he/she named the child a name that is exactly the opposite of the child's essence. What if the child hated his/her name? Would the parents regret naming her that? What if that happened to Peter Merholz, coiner of the term "blog?" What if Peter Merholz woke up one day, after the term had become popularized by Pyra Labs, and cried out in despair: "Blaaaaaahhhh!!!! Why did I name it a 'blooooogggg'!!?"
If I were him, I would regret it too.
