There's a difference between "good idea" and "marketable business." As founders, we have to make that distinction. I'd like to see YC do blind interviews because I think it's a good idea for them to do so. I am not working on that myself because I can't see that good idea, in and of itself, turning into a business--a product a company could replicate and sell to others.
Perhaps other founders have the necessary domain expertise to turn something like what I suggested into a replicable, marketable business. If so, I support them in doing so.

I did. I took time away from my business to write this comment and make a suggestion. I hope YC takes it into account. I think it would make an awesome experiment for them.

I suspect this might have been your real point. Sure, YC has worked well...but could it work better? Those are the questions we as hackers ask all the time. I think it's worth a shot to try something different and unique that could work even better than the status quo. Given the popularity of my comment here, I'm not the only one who thinks so. We'll see if YC (or any other accelerator) runs with this suggestion!
