I posted it at a time when there was a lot of other stuff getting posted so it got buried really quickly. And now I feel discouraged to post it again...
I follow (and am followed) by several HN'ers and I've noticed that sometimes they will tweat a title and link to something they've posted (or found interesting), and I usually click through and (if I find it interested) upvote it. Use your network, and don't be discouraged, I'll vote for your stuff :)
