Twitter can be unforgiving country.
In yesterday's editorial, I touched on the issue of cyber bullying.
Bullying is bullying, no matter what form it takes, but the modern day phenomenon of online attacks, intimidation and general nastiness has opened up a new world of opportunities for bullies.
And for those who didn't know they had it in them.
People who might be perfectly nice in real life come over all Mr Hyde when they hit Twitter. Those who wouldn't say boo to a goose seem to have no trouble getting into a rabid argument over the most offhand of remarks or throwaway comments.
