Quite a scrabbler in my downtime, since becoming a full time painter.
I've read a range of material that analyses the psychology behind games and conversations in cyberspace, and it's described as a weird combination of reality and fantasy and a whole new place in your brain to occupy. The place where conversations takes place is more like a 'dream' than anything, but made challengingly real by the 'presence' of another, the coming and going, the meetings in real time.
Scrabble got me into writing online generally, switched on a narrative voice in my head which has been quiet amidst the demands of a full time job over that last 13 years. Talking to friends through scrabble has become a place to condense and distill ideas, a discipline in communication contained within a bubble.
