How the Entrecard droping help's you?

Last August I got no opportunity from paper post because real rank was high, my friend advice me to sign up to the entrecard site and drop my entrecard to every blog I opened. When I started to dropped 300 everyday my real rank is getting down and it help me a lot.
Thanks to all blogger who dropped my Entrecard. I am planning to delete those blogs that I save on my bookmarks who did not dropped my EC anymore and changed those blogger who dropped my EC, because it's unfair when you dropped your EC everyday for several times a day because you have several blogs too and those blogs did not drop your blog.
