Somewhere earlier you said that its a good thing to have careful discussions about sourcing and right about now you may be coming up against be careful what you wish for  Im pretty close to agreeing with you and I do recognize that this discussion is going on longer than the corresponding page content merits I think we agree that context matters and that most sources are not ipso facto appropriate for everything I think we can agree that the Arjo paper isnt quite enough to source the Twitter data but I hope that we can do it without portraying Arjo et al as being suspect about everything
