Background
Recently I noticed a few posts that link to external website links. These posts use the external links as the core of the answer.
Example
This is one example of a short post with an external website link: Example 1
Questions
What is considered the proper usage of a external website link?
Thoughts
Using website links as answer seems risky as the website link could become obsolete. A lot of answers refer to scholarly articles, therefore I feel this question needs to be addressed. I think quoting the article makes since, but if that is the answer other questions arise about how much of the article should be quoted.
