Definitely need a new listing site. Great to see this effort. Almost everything I try to use as you say is outdated, my suggestion also is to use a geographic categorisation (by country maybe, or by where they ship to). I got a whole lot of sites from my country that mostly, when I visited, actually either no longer accept BTC or the people who run the shop don't know how to operate it.

One more thing: might be a good idea to list the payment processor. As in, Antonoupoulos using BTCPay Server and thuisbezorg using BitPay.

Another thing, I think the effort needs to be spread out, or somehow linked to Google or some other big service like that because the moment you stop updating, you get yet another site that becomes old and outdated.
