Hey bayou bill, I don't believe there is a definitive answer to your query.
I post a LOT of "songs" on the songs forum. I get very few comments or listens. Though I wish everybody loved me, I realize that is impossible, so few comments or listens are out of my control.
I also don't comment on many songs myself. I listen more than I comment. The amount of quality music on the song forum is staggering.
I think everyone posts or does not post for a different reason. In the big picture I'm not sure it really matters. Peoples comes and peoples goes, there is an empty chair waiting for you, where the last person sat, before they passed, or moved on down the road. Once your off the front page, all your efforts become part of the collective heap, and we are all equal still.
I look forward to hearing your next song on the forum.
