First of all, almost every board has 30-40 "lookers" for every one that bothers to post a reply.
Some of it could be because most lookers aren't registered, or those that have, are suddenly shy about leaving an audit trail a suspicious spouse or significant other might track and use against them.
Third, a lot of us are plain and simply, lazy. Why bother to stop and type a lot of fulsome praise and kind words about how "swell" your story was and thank you for spending a week, or two, editing, re-writing and honing it to the point you weren't ashamed to post it under your (nick or avatar).
I finally gave up (years ago) wishing people would tell me how my drivel "changed" their lives and made them finally come out to family and friends and move in with their same sex "dream". Now I just write whatever I want (or what someone asks me to write for them, rarely actually) but I'm happier now.
So please don't agonize if nobody acknowledges your hard work.... in fact, I think it's more fun for me now just "writing" and not worrying whether or not anyone reads it, or even cares. It IS liberating, there is that!
