Twitter closed down our efforts to share post-Osama bin Laden Twitter data (or any other collections) for research purposes, again citing their TOS & API TOS. http://bit.ly/l8DSA3 To be clear: we were giving the data away, not selling it. Also, it was not scraped of Twitter. Rather, it was gathered using a Twitter-authorized account and an API that lets us fetch 1500 items at a time. It is a shame that the now 2 million tweets cannot, for example, be sampled and coded using a crowd source model. Or could they? I am assuming the provision against sharing data does not extend to individuals who gather it and keep it to themselves or work with it in a research team. ~Stu -- Stuart Shulman President & CEO Texifter, LLC <http://www.texifter.com/> Have you tried DiscoverText? http://discovertext.com *Featuring the Facebook Graph & Twitter APIs*
