what's the difference? isn't the content of the article that is the more important? The number of surgical abortions per year is a fact that can be easily found on the net.
You said -- "what's the difference? isn't the content of the article that is the more important?"
It's by referencing links to verifiable sources (or even some source), as opposed to "vanity posts" that one is able to evaluate the veracity of claims made.
As it stands, I don't know if this poster made this up or made a vanity post, or is collecting information from a variety of sources, some trustworthy, some not.
So, in this case, it's more important to know the source in order to know if the content is correct or not.
