SL-wide/Primfeed promotion service for DJ's and Performers

When I saw the EasyBloggers storefront, I had an idea, what about a directory slash promotion distribution for DJ's and other performers in Second Life?

Currently I push set notices in various SL groups, also on Discord via several servers, as well as on PrimFeed. It's quite a bit of repetitive work to promote a set. It would be really cool to subscribe to a service that does that for me, based on type of sets, genres, and sim rating for the venue. I suspect that this is another "if you build it, they will come" situation!
