Awesome site, very useful info, freely editable, user-friendly. Only problem is unrestricted access to "adult" topics, but it is an encyclopedia after all.
Good site. Inaccurate at times (see: Marijuana article) and pornography is present (see: Nude). There is not safety for children who may search inappropriate topics, such as sex and kamasutra. Parents should be teaching these things to their kids, rather than a Wikipedia article which may confuse them but at the same time, entice them. Supervision is required.
