Periodically, @mtgred posts stats on jinteki.net usage. I think the most recent report is here Jinteki.net game stats January 8th - March 6th
I’m sure that whenever minh/other devs want to take a break from the incredible string of updates they’ve been delivering recently, it will be an interesting data dump to look through.
edit: though maybe best to wait until post-worlds in case people are worried about players getting an edge through this data. After the scraping kerfuffle I’d rather just stay well clear of that issue for a minute
