Care to elaborate?As for breadth of support, it is a well-known issue that IRV may eliminate a centrist candiate too ealy, if he gets insufficient 1st-choice votes. If anything, Approval Voting is more geared towards a consensus candidate.Note that with this scheme, not ranking a product is equivalent to ranking it *last*. (Correction: it's actually even worse than that if you have multiple unranked products.) That seems hardly fair to the products you don't know! (And is precisely the situation they were trying to avoid last year.) It is possible to deal with unkowns in a more fair way - essentially by extrapolating from the rankings other voters gave to the product - but that complicates the system quite a bit.In Approval Voting, you are asked to draw a line between one set of candidates and the rest. This implicitly forces you to make an estimate of the quality of the unknown candidates. For example, the ballot might consist of two ok products, one really crappy one and two you don't know. Under Approval Voting, you may decide to vote for the two ok products and the two you don't know, under the assumption that any unknown Ennies nominee will likely be better than the one product you know is crap. This is an entirely reasonable and acceptable vote, based on your estimate of the quality of the candidates. Or if one of the two "ok" products is instead a superb work of art, you may decide to vote only for that one, under the assumption that the two unknown are likely not quite as brilliant. Again, a perfectly valid vote. The upshot is that Approval Voting will give an unbiased estimate of the quality of partially unknown candiates, without having to add any mechanism to deal with them explicitly.</blockquote>
