In a white paper that will be made public Jan. 29 TuDiabetes.com is mentioned as an example of a successful health social network and an interview I had with the author of the document a while back is published on pages 25 and 26.
Note: last night, I posted the URL to a pre-publication version of the white paper not realizing it still needed to have a few more corrections. My apologies to those who may have downloaded a copy. Please check back after Jan. 29 for the final version.
