Somewhere earlier you said that it s 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 I m 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 isn t 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
