BlogShares - Fantasy Blog Share Market - what a great idea! I remember a game like this that used to be played postally. You traded currencies in parallel with a current Diplomacy game. The prices varied with trades, and you lost your holdings in currencies of countries that were eliminated . I did very very badly the only time I ever played, well below random performance. The experience helped me form a conviction that I should never speculate in real markets like the Stock Exchange - a conviction that has served me well ever since. But I will certainly try playing BlogShares.
