I'm not sure how long it takes to update. I added a link to this one when they first launched, and they had to do some additional troubleshooting to get it to appear. Maybe it has some sort of trouble handling edits... Hopefully @pennsif will follow-up if it doesn't come in on its own.
checked this morning and @pennsif's system updated this on the map!
Sorry for the delay in replying.
Look out for the new version of Steem Atlas in the new year.
