Why do postings get no response. Is it that mine are boring?  

here I responded to one of your posts. I don't know why your other posts are not getting responses.

No, infact your postings are probably really interesting and well thought out and this is why people don't want to reply. People seem to like the discussions which require little to no thought.

Your discussion is never to dull actually, i was thinking that my discussions were dull until i realized that there are several thousand of new discussions posted every hour. With that amount of discussions, you will realize that our discussions with only be there for a min, or less. And people who usually sees it, and responded to it, only resulted to few responses to the discussion. That resulted in a dead thread where people will not see that its active, or it will be left, far behind the newer, and latest discussions. I am experiecing that too, its just that i do not focus on that part now, i focus on responding that creating new discussions. Since they never get much responses, why bother to create them? Its a waste of my effort, and brain juices. Well, that is how i feel at least for now.

It is virtually impossible to assess the reason why certain discussions get vast responses and others receive very little. I have no discussions with no responses, but I do have a couple with only 1 response and quite a lot that have attracted only 2 or 3.
It could be a simple matter of luck and timing. There are members to whom your discussion would appeal and members to whom it would not, so if the right audience is offline at the time then your discussion could move down several pages before they sign in. As a result your discussion would only be noticed by those to whom it was not of interest.
