I have just launched ABillionBits.com, (http://www.abillionbits.com) which includes display ad, page driver and SEO features. I built and designed it myself using Drupal open source CMS and standard themes.
The goal of the site is to attract one billion entries, each of which provide a front page picture, a full information page to which more images and site links can be added, and a front page page driver link. SEO is provided through keywords, site SEO optimization which also benefits each entry, subdomains etc. My initial market is mostly small business, but once word spreads it would attract larger enterprises as well.
My main concern is how I am presenting the concept and the "story" behind it, and that the site instructions are clear. It is a pay to post content site, but I will gladly set up a free account for anyone who would be able to review the ease of site use. Please contact me via the site messaging system and I will set up the account for you.
Thank you for your assistance,
