The dual track format made it likely that participants' tweets at any given time were directly related to the themes of the presentations and discussions scheduled in one of the two sessions on the conference agenda at that time. (Note: The "RangelChat" app for iOS and Android was also enabled users to follow session by session.)
Below find the DLL Storify of tweets that were generated by participants who used hashtags = #4Harlem, #SiliconHarlem, @SiliconHarlem, and other hashtags that emerged in the Twitter stream. As usual, this DLL Storify is merely a "firehose" draft, i.e., it includes tweets in chronological order without comment or classification ... Storyfies of other #DiversityInTech events are listed in the DLL Archives.
On Tuesday 10/20/15, the Internet Society, New York Chapter (ISOCNY) published links to videos of all of the conference sessions. Viewers can now watch the presentations and use the tweets in the DDL's Storify to learn what conference attendees thought about each presentation.
