I've been using Wikipedia since it had an impressive 40,000 article count, inspired by the potential of a free source of knowledge for all. On Wikipedia, I mostly handle articles on Judaism and Computer Science.
I consider myself a Jew with mystical leanings. My favorite Jewish philosophy is tikkun olam (fixing the world), which is the obligation of every Jew to promote social justice, and ultimately bring the world to utopia.
I am interested in situations where religion and science intermingle. As such I am an avid believer using science, and especially Computer Science, as a tool to reach the singularity.
