Hi all - I'm the founder of Ranker and as @bertoletdown says, I'm also a Phan (fave shows attended: Big Cypress, Festival 8, Long Beach 2012, Ventura 97/98, Vegas 98). To be completely honest, when I just now saw this live and the huge amounts of votes and comments in the first 20 hours, i got a *little* choked up . I launched Ranker about 4 years ago and this was exactly the kind of thing I envisioned - we've since built a growing, successful site but running an internet startup takes up so much of my time that I never have time to make content like this - really granular things that mean so much to a community, and where Ranker can hopefully really add value. We have 1000s of great rankings, but things like Best NBA Players Ever Funniest Movies In History just don't go as deep and unique as something like this. So thank you.
To address some specific comments for future lists - we could potentially offer a version that just has upvotes and no downvotes (personally I prefer including downvotes, but I understand the argument against it). It's something that we've already comped out and were planning to offer at some point. In the very very near term, maybe as soon as next week, we'll be launching a version that you can "rerank" from and a link to your personal lists would save to the widget on phish.net.
Oh and btw my personal 2cents on the list - I haven't had time to listen to the majority of these jams yet, but I do agree that the Holly Hood (the only show of this tour I caught), excellent as it was, is probably a bit high. But of course that's what makes opinion-based rankings so interesting . . .
