On the Value of Wikipedia I attended an anniversary party for the tenth year since Wikipedia's founding, where I met the inventor of the Wiki. That night I understood how powerful and important Wikipedia (and the Wiki more generally) had become/was, remains and will be.
Wikipedia represents (as a single instance) the general global population's (humanity's) attempt to educate and fortify itself through open and accessible information. An effort that has not only been successful, but has been integrated (as a foundational VIP) into other everyday technologies; such as Google Search.
It's fine if other (more exclusive) bodies of information don't want to participate with Wikipedia, it always has been okay. That isn't what Wikipedia is for. Wikipedia is (free) for the average person. There are as few barriers to entry and is feasible and sustainable for the platform.
Of course it would be a dramatic improvement if other (more exclusive) bodies of knowledge wished to merge with Wikipedia, or offer their data and expertise. But that is a topic for another thread. What matters is that Wikipedia is an open, useful, reliable and outwardly referencing body of knowledge; some might even say wisdom.
