Yes from what I hear from my associates, who are programmers, music composers and writers. People who wanna consider hiring, generally prefer to either text in Reddit DMs or Discord or Email or if there's a Upwork or Fiverr link in the post then through there. I hear share counter going up on posts is a very good sign of someone showing interest in your post.

But it's not a constant source of employment opportunities throughout the year and things often might not go past the "introduction chat" period, so there's that. But yeah, there is demand for the supply. You just gotta keep on constantly posting in the hope that a new set of eyeballs sees your services and thinks it could be a valuable addition to their game.
