Personally, I thought the snackkeys sale format was better.
Maybe that's because I got in on that one.
But it's also like - you're probably only going sit there F5ing if you really care about getting some. Maybe some speculators are going to care enough if the artisan is underpriced relative to what it'll garner on the trade market later on. Of course, it's tough to do this in a way that no one has time zone issues, work issues, etc etc. But it's just a lot easier to throw your hat in the ring for a free raffle and I would guess that leads to more entries that just have future trade/sale in mind. Just a guess, of course.
Maybe some combo of the two would be better for next time? A round of raffle, a round of F5 mashing, repeat...
