I recently joined the new Ello network and there are a TON of artists of all types. If you want some idea of what Ello is, check this LA Times article.
One of the great photographers on Ello has compiled a list of other photogs.
Ello is still in BETA and invite-only, but if anyone would like an invite, let me know. First-come, first-serve. When I run out, you'll have to wait.
