"Supporting information is available for this article as text files. See below for the links."
Providing datasets as text files is much more useful than making them available as PDFfiles (hamburger, anyone?). Recently a colleague of mine, Dave Palmer, published a QSAR model of the aqueous solubility of organic compounds. I'm not sure whether at the time it was possible to provide the supporting information as a text file. In any case, the test and training sets are available on the ACS website as two PDF files rather than as text.
Thanks to the magic of the Chemical Blogspace Greasemonkey Script I can alert anyone who visits the journal website that the supporting information is now available as text files.
