One thing that may hurt the popularity of Vintage is that Vintage tournaments aren't available in many states. If you look at the tournament reports forum you will see that only 15-20 states run Vintage at ALL, and in some of those there's only one tournament every few months, in one corner of the state. I find it amusing that we're worrying about proxies (and suggesting the use of doubly marked cards (backs AND corners) but not mentioning the fact that most US states have no Vintage tournaments advertised on TMD. Now, there may be tournaments going on somewhere, but I doubt there are any serious Vintage tournaments in the US that are totally off the radar.
This was said in the discussion about proxies and vintage, but I felt like it might be helpful here considering the goals of the ranking system.
Perhaps there could be some sort of extra inventive for bringing vintage/participating in vintage in a previously non-vintage area. You could do it by state, or by region, or whatever. That is so easy to discover that it suggests conspicuousness or little need for perspicacity in the observer. that requires more investment for Dan and Eld, but maybe someone else would be willing to donate as well.
