I prefer the article and a link.
Sometimes I go into the links, but many times, I don't have the time, or am too lazy to do so.
I would say that if you have the time, take the time to post the article and go through the cleansing process. If not, post the link.
It's always helpful to have a brief summary there if all you post is the link........... so that I know what to expect if I do happen to go to the link.
