Henri Rantanen, aka. nerdaxic
I try to use the screen name nerdaxic on online interactions where possible.
Henri Rantanen is quite long and boring, so a short, unique, descriptive and difficult-to-pronounce nickname makes me easy to find across multiple sites and services.
The name originated from an online random nickname generator tool, me being a nerd and word being an adjective. It is different enough not already taken and as an added bonus, it sounds like some sort of medicine.
