I'm against the softfork, ideologically. But I do think it's a clever way to go about it. I realize that basically nobody's vote will oppose it. But that doesn't mean we cannot determine the opposition.
Specifically, I want to see if we can approach the 12M SP mark, which is sort-of the high-water mark for the last "fork-them-out" vote, based on the capped measurement use to register votes in the Steem Foundation, if I remember correctly. Remember that they weren't voting on the fork, but instead, the formation of the foundation. It's not apples-to-apples. Just a look at magnitude for comparison.
If we can reflect similar numbers, I'd see that as enough data (and only data) to go on for determining what the "regular users" level of interest is in this course of action.
