EDF Charades is a classic free exchange of goods with added mutual benefits. You are at liberty to provide your interpretation of the EDF charade market, and I am equally, and without prejudice, able to extract value from that interpretation. Social benefits accrue incrementally and conform to a pure distribution of need. That you seek to undermine this market with weighted, or means-tested, offers of determination, ignores the fact that all posters have the equal opportunity, right, and means, to guess the subject of the charade. I would support, have supported, and do support, a return to these free principles of choice in determining the outcome of the charade - and the rewards, accruals and supplementary benefits (monetary and social) that occur. In short - your guess.
