Ryan Naraine has an interesting interview with LMH (the person being MoKB):
RN: Can you introduce yourself? Who is LMH? Is there a real name?
LMH: Well, I have a name as we all do. LMH is in fact a reference to my real name. The reason for 'hiding' behind it is that while I don't mind appearing on public mailing lists, news media, etc., I want to be recognized by the work I do. A name is pretty much like a trademark, and I'm not into trading with my name, thus I prefer to use a rather simple nickname such as 'LMH'. That way people focus on the work and not who has done it. It's also good to keep a low profile sometimes. I'm based in Europe.
