Snaketales has a dual origin
At uni while working on the student newspaper I was known as 'snake' for
1. being 'lower than snake's balls' in scamming freebies (I didn't scam them, I just made sure I was first for concert reviews, etc

)
2. being cold-blooded when it came to subbing/re-writing stories.
After uni I labelled one of my emails to a friend as 'snaketales' i.e tales from snake, and I've used it since then.
