I agree that was the problem with how the questions were set. It was impossible to determine how many people were actually OK with either codec, and how many with just one of them. If we are to repeat the consensus call on the list, we will at least learn the distribution between "H.264 and VP8" vs. "Only H.264" vs. "Only VP8". I would suggest that if either of the "Only X" groups is relatively small, we could declare rough consensus.

Yes, so it would be useful to know what the proportion of those people raising their hands for just one vs. both options actually was.
