As you may have noticed, I've just removed the BlogRush widget few days ago. In fact I was not satisfied with the quality ... ehm ... the quantity of traffic it brings to my blog. And now, it cam to my knowledge that BlogRush team have decided to shut their service down. It seems that they were listening to me :)
