Add BGANS to PopRank

PopRank is an aesthetics ranking website where people are allowed to vote on NFTs in a heads-up battle. This then allows the website to rank the collection in terms of "aesthetic rarity". We've discussed this kind of app in the past, we've talked both about getting BGANS added to an app like that or building it ourselves.

PopRank now allows listing any collection for 0.2ETH. I think that will be money well-spent and I think it will be an enjoyable app for bastards to use.

PopRank also allows you to list+feature the collection on the main page for 1 ETH total. This could be interesting to drive some more traffic to the project, but the value proposition feels less clear to me than just the base listing of 0.2ETH.
