File this one under ‘you learn something new every day’.
I may be the last person to know this, but example.org, example.com and example.org are domains reserved for use in documentation.
I tend to use ‘mysite.com’, ‘domain.com’, ‘yoursite.com’ and anything else. I usually try and remove automatically generated hyperlinks because I don’t like to feed link juice to the owners of these domains. But it still happens.
Then today I accidentally clicked on an automatically generated example.com Url, and found out it’s reserved for documentation. No more link-juice bleeding from documentation and discussions about Urls. Try it! http://example.com
I’m off to do some find/replace.
