Hmmm... yes interesting indeed..

I meant that is it worth the investment in time, uploading to a site that you couldn't imagine will do well, anyway? I will upload to some sites because I respect their approach and their business plan, or their potential. If one of those potential sites pulls thru, then its worth being on board when it does. Its not worth it for current earning but for future earnings.
I will continue to upload to Crestock, SnapVillage and Yaymicro (when its released) because they are sites that i have and will buy images from, and can see legitimate reasons why other people would too.
