.org doesn't mean credible!
Many textbooks, online research guides, and other resources claim that a .org domain name is an indicator of credibility. The common explanation is that only non-profits, professional associations, and other organizations are able to register a .org domain name.
Unfortunately, this simply isn't the case. The reality is that there are no restrictions on .org domain registrations.
Anybody with about $15 to spend each year can create one. Hell, that's what I did.
