It is the main way steemit users communicate and share their work and network. There are tons of groups I can invite you to and you can start meeting more of the community! @rmae is a page I made to help out the local artists (I'll get on there and resteem your post today), and @rockymtnsteem is a group that pretty much got me on Steemit and has a lot of members in Denver. Both have discord groups as well. We also have been coordinating physical meetups, and there are a couple other music makers besides us in the group (oh yeah I make music too and play guitar!).
