Absolutely. Big businesses plan for that delay before the sales come. They don't expect customers to be beating down the door right away. Yet WE want the sales/bid fast.
And consider we rely on google to fling our items into cyperspace, ebid members to notice us, our old buyers to come back, etc. That takes time. As you say, everyone has to work at it too.
OP will notice too, that what you just did, encourage, is something that is common here, but not on other sites. On ebid, new sellers are helped via the forums or even by PM for the shy ones. Everyone is willing to help others because when the new seller gets that first sale, its as great as watching our kids take their first steps.
