The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Happened as dated, per techcrunch.com[2][3]: "…batches of 250. The first batch is now available at: https://www.eventbrite.com/e/hackathon-at-tech…"
TechCrunch's[1][3] own dispatch, timestamped 3:20 PM PDT on 6 September 2014, reports the Disrupt hackathon "just kicked off" at Pier 48, falling within the pin's stored 5-8 September 2014 window though the actual kickoff was 6 September.
TechCrunch's[1][2] agenda announcement (published 28 August 2014) confirms "the 24-hour event starts on Saturday, September 6, and runs through the night", corroborating the hackathon's start date within the pin's stored 5-8 September 2014 range.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most. A picture that shows something else, or shows it badly, is looked at too, and moved down or replaced.
