Ask HN: Is it worth to advertise white paper on itwhitepapers.com?

I would like to hear thoughts from someone who have advertised their white papers on this website.

I have found one media kit for ad age where they are charging $35,000 for 6 month listing. Here is the link:http://adage.com/images/bin/pdf/Ad_Age_Media_Kit.pdf What other options are available in market and what are their charges?
