I've now completely stopped dropping cards (unless I just happen to be on a site with a widget) and have noticed no difference in my traffic at all. However, a lot of people are still dropping on my widget and purchasing advertising on it.

I've been using the credits earned from this in the Entreecard shop rather than using it to buy advertising on other blogs. I can spend 150 EC and get someone to stumble or digg a post - this brings in more traffic than Entrecard alone, and in general, the traffic is better than Entrecard traffic.
