If there was an option in Tally to hide votes so they don't influence decisions, it would be more useful. We used it at Techstars recently and didn't find the results very accurate. That said, it's very slick and simple, which I really liked.
That's a very good point Patrick. It was intentional because I didn't want to add extra buttons and clutter the interface, but I might rethink it. It's always tricky to add functionality without sacrificing simplicity.
