It's an interesting concept. Reading some of the comments here, I think there's a fine line to tread between creating something which is too formal, structured and academic, and something which is too gimmicky and meaningless, and actually de-values people's opinions. There must be a middle ground here though - or are they mutually exclusive? There is a fundamental difference in an opinion and an argument, and I wonder if some of the formal aspects (i.e structure) of an argument could be utilised to make this a place for intelligent discussion, discouraging opinions which are just opinions. The ability to research and reference related content could be crucial here. On another note, would be interesting to be able to see the stats related to opinions/arguments easily - the data could provide some really interesting info, if enough users got on board.
