A while back I explained what Orders of Magnitude is all about as it's one of those overused but poorly understood terms. In the same vein I was pleased to see Mark Harrison's explanation of Zero Sum Gain. It's a phrase I hear a fair bit from people like Bill Gates and others but I never really took the time to understand it - I also thought it would look stupid to stop Bill and ask him :)
Here you go then - Zero-sum game explained
I have to admit, I was a little concerned when I saw an incoming link titled "buzzword bingo".
Glad that my little explanation has cleared this up. The reason I wrote that post is that I'd used the term elsewhere, and it had caused confusion...
... good to hear I'm in good company.
