...and it is also the consensus solution of most people I know who oppose slate voting.
There are a couple of irrelevant things in his piece that I disagree with quite a bit but, on most of the details and the general tenor that, again, was a reasonable piece. But I'd say two things against the main point: first, changing the rules when you don't like the outcome really does look like everything the SP says is right and that the ASPs are trying to restore the system to its previously gamed level, no matter what the changes are. Again, I side with Martin here about not changing things, at least for another cycle or more. Maybe the SP slate doesn't work next time of its own. Maybe the ASP slate counters it fairly. Just wait and see - don't set into motion a cycle of rule changes designed to engineer the "right" results. That really would destroy the awards.
Second, I'm in the bizarre position of being an 18th century English gentleman decrying giving the unpropertied the vote.
But when I say to get as many people involved, I mean "who are SF fans". This isn't literally democracy which affects everyone, but an SF award. There's no litmus test to decide who's "really" an SF "fan" but the 40 buck barrier is very high (perhaps too high) but not insurmountable for a lot of people. (I don't know where precisely it should be set or if there's a better way but, as I said, any of that would involve rule changes and I'm not in favor of that at this point.) What dropping any sort of entry barrier does is truly open the floodgates to madness. I don't even know what "gamergate" is (that seemed out of the way enough that I didn't bother to track down those links) but if Worldcon changes the rules to drop any sort of barrier, you might as well open the floodgates to every looney and just hold an internet poll. A lot of people love to make the casual troll but it takes a pretty dedicated troll to spend 40 bucks for it. More participation is good but we're still talking on the scale of "SF fans".
I think that what they did was too much and without a solid basis because it was so easily debunked. They really went about this the wrong way. Subject should have been properly explored and arguments supported by hard facts that should have warned the voting body of possible existing bias. Instead, they went to campaigns which only served to make it all worse. What they did, definitely doesn't help the balance they claim to be supporting.
As I mentioned regarding Martin's "beef" post, I don't think it's quite so easily debunked. But, leaving that aside, Correia is, of course, not a disinterested party, but this is SP
3 and SP1 seems to be almost a retroactively characterized thing where it was basically talk, just like you're saying and he was pre-emptively villified. So that begat SP2, where a single nominee was put on each category and I think they all lost and he was villified and the ASPs declared victory in gloating and unseemly terms. (I was unaware of SP1 but I saw this with SP2.) And that begat SP3 in which the SPs said, "We were only pointing out a problem, which was ignored. Then we were making a point, which was ignored. So now we're going to win. Ignore that if you can." So this SP3 thing didn't just burst out of thin air a couple of days ago (though it seems like it did to many here as they've said) but they did go about it by initially arguing and weren't "debunked" by hard facts but attacked with innuendo and outright fabrication. Now, I'll say they went about it the wrong way by letting themselves touch, e.g., Day with a ten-foot pole, for instance, but they're kind of stuck with him by the principle of free speech and competition being decided in the marketplace and not giving in to "SJW"s and so on. The ACLU supports the rights of Communists, Nazis, Green Peace activists and the KKK to march and assemble and so on. Ironically, the ACLU is usually regarded as a bastion of liberality and villified by many conservatives, but the principles are the same. Be all that as it may, the SP thing didn't just start like this yesterday, but is part of an ongoing process.
And, to wind back to what I was saying about rule changes and hasty action: the ongoing process may result in disaster or improvement. Let's give it at least another year or two and see.
