Add weighting to certain choices made by voters which is then automatically displayed with the results - rather than having to work it all out separately at a later time or get them to use an excel sheet (which is what I have to do now)

For business enviroment it would be useful. Weighted voting: when not all voters have the same amount of influence over the outcome of a vote (eg. for shareholder meetings, where votes are weighted by the number of shares that each shareholder owns)
