There are… a lot of proposals, but you don't need to rank them all. Skim through the list, and find the few you really care about. This is an experiment, so we're also interested in feedback on the app itself, and things we can improve for next year.
As an experiment, we (the Firefox team) wanted to try a new way to get feedback on which Interop proposals matter most. So, here's a web app where you can rank the proposals you care about, giving us data we can use when reviewing which ones to champion. interop-rank.jakearchibald.com
