I got this email today from Entrecard:
We are pleased that many members are taking advantage of Entrecard services and that Entrecard is able to help users increase traffic to their blog. However in order to continue providing this free service, we will be taking 15% of our entire ad network inventory for sponsors as of Sept. 28, 09. This is a standard business model used by free advertising networks. The revenues generated by our sponsors will help cover overhead expenses and keep our service free to all our members for years to come. To keep things simple and fair, all ads will be distributed evenly in our network. We are currently working on a feature that will allow users to disable sponsor ads that may conflict with their blog. This will be available in a few weeks.
Please be assured that we will screen all sponsor ads to ensure that they meet our guidelines. All sponsor ads WILL be family oriented, and will not promote nudity, violence or anything illegal.
So paid ads are coming back? I guess it's better than that 50/50 split they had before, but I'm still not coming back to EC anytime soon.
