One thing that's always been a concern with EC is the high "bounce rate"--people stopping by your blog just long enough to earn a click. Entrecard has just made this announcent on their blog:
Starting soon, “dropping and running” will no longer give you credit. We are developing a proprietary algorithm to determine whether or not you engaged in the blog you visitied in some way. If you did not engage in the blog, you will not get credit. We won’t be disclosing exactly the algorithm we use, so that people can’t game it easily.

I'm not really sure what to think of this. As I've mentioned before, traffic is traffic--I don't think it is EC's job to make sure people hang around one of my blogs. I'm afraid this technological intervention is going to cause more problems than it resolves.
I'm still not sure how much longer I'll keep using EC. I thought all the changes would mean we (the bloggers) would be able to keep more of our credits. It still hasn't happened. Right now I don't really see that I'm getting much traffic out of EC.
