The only problem with that line of thinking is that I think that even with a deadline that is ten years from today, there would be missed matches that are praised as a great. There is new stuff every day being put out by companies. There is new stuff unearthed every day that is great too.
I understand your position, however how much did people watch in 2006? Let's do it now and then, hopefully, again in 2026 and see where people are in viewing footage then. I don't see this project as a one time authority piece, I see it has a another step in an ongoing process.
In an ideal world, every ten years somebody will re-visit this topic. I would love to see what the poll would look like in 2026, 2036, 2046, etc...
