Here's an alternative suggestion:
Don't take 15% of user's ad space on a daily basis. Instead, after six standard Entrecard ads are purchased on a blog, queue a sponsored ad in exactly the same way. A sponsored ad will then run every seventh day for 24 hours. (14.29%, close enough?)
- Standard Entrecard advertisers won't lose 15% of their ad time.
- Sponsored ads can be cancelled like a normal ad. Depending on how popular a blog is, the blogger will have up to 12 days to cancel an ad before it runs.
- Bloggers get paid in credits for running sponsored ads.
Here's another suggestion to monetize Entrecard. Place sponsored ads on the Entrecard blog, dashboard, profile pages and forum. How can Entrecard expect users to run sponsored ads when they're not displaying ads on their own site?
What's your opinion on this latest move by Entrecard?
