How does the community help society at large?

Simple, it helps by researching developing and creating thing to aid and benefit mankind. Initially this will be by working through and for existing organizations offering peer review of scientific papers, computer applications and technical support at low rates. Especially it will try to help organizations which offer something free to the world (citizendium, wikipedia, linux etc.), organizations that are trying to help heal the world (WHO, Medicine sans frontiers etc) and ultimately independently help educate local and international students for nothing to improve education for all. The only thing that limits the community is its size and the dedication of its members.
