Major Pinging Issue

Dear WordPress community.

We have been experiencing some problems with setting up auto pining of our content upon publishing to other networks like twitter, facebook, technorati, etc. I researched the matter, tried using numerous plugins, and used the Settings – Writing – Update Services within WordPress. None of the tools available were able to auto distribute our content upon publishing.

We have the following services set up in the Update Services:
