Absolutely I could see how that could improve credibility of whats being posted for sure. Its harder on FB than a forum where you can combine it in one post - and often I dont add extras in as I get so very time poor. But also people share loads of information across the web, all of the time - its not the norm adding in history of where the article came from unless a site has specifically published that article.

I also think we all need to take just a liitle bit of personal responsibility too Especially when researching something as serious as whooping cough. I am am 'about us' reader
