Sorry, I wasn't talking about your answers specifically, but about aggregate results. (Also note that I think you might not get presented with all possible features when taking a single survey.)

The point is not to find the features that people would like, but the features that people would like most.

Additionally, this allows you to find a few features that have particularly high value for a subset of users, even though on average they're not that interesting. (I think Multi-Account Containers are a good example of that: too much of a hassle for many, but for some people, like me, a reason to never switch away from Firefox.)
