My pensieve

I was trying to add a twibbon on my gravatar to support 5 years of Mozilla and I got the following error from the server. It made me realize that twibbon and twitter must be running on windows server. Hence thought of shifting immediately to identi.ca. The error is following. Hope it will be useful to crack into the server. ;).
