If I am incorrect about downvotes being inconsequential account-wide, say so and it might be possible to work out a different system.

Wouldn’t “upvote if you have never heard of it” accomplish the same thing?

I guess it would depend on people reading and following the instructions, instead of just upvoting games they like. Maybe that’s a bit much to ask. :P

I nominate Paul Eggert and Arthur Olson before him, for the tz database, which we all depend upon whenever the time at which something happens (or did or will happen) matters.

Edit: Tom Scott touches on the subject here.
