Factual Their own work or organisation

When Zuckerberg started Facebook, people mostly typed text on websites.

Mostly true True in substance, wrong in a detail.

Factual: Statements about the present or the past, checked against the record: did they hold up?

The second judge would not resolve this claim; the verdict shown is the first judge's.

Said for an organisation they lead or work for; it counts on both records.

What would count as true or false

The claim is that when Zuckerberg started Facebook (2004), people mostly typed text on websites, meaning web activity was mainly text-based and on desktop rather than photo, video or mobile-app based. True: historical data or accounts of the 2004-era internet and early Facebook show that text-based desktop web use was the main mode, with photos, video and mobile apps marginal. Mostly true: text-based web use dominated, but photos or other media were already significant enough to make 'mostly' a slight overstatement. Mixed: text and other media or modes were roughly comparable. Mostly false: there was a real text emphasis, but non-text or non-web use was large enough that the claim distorts the picture. False: evidence shows text-on-websites was not the main mode of internet use in 2004.

  11. E11 A brief history of Facebook as a media text: The development of an empty structure First Monday (author: Niels Brügger) · 29 April 2015

    “These analyses were produced at a point of time in Facebook’s history when there were limited options for profiles and networking and no status updates, News Feeds, Facebook Connect or apps for mobile media.”

Reasoning

Accounts from 2004 describe early Facebook profiles as mostly typed text: concentration, phone number, hometown, favourite books and interests (E2). A 2015 academic history says the early site had no News Feed and no mobile apps (E11). These support a text-based, desktop picture. Photos were already part of it, though. Users uploaded profile pictures from launch (E1), friends' photos showed on profiles (E3), and photo-sharing sites such as Picasa, Photobucket and Flickr existed by 2004 (E10). The evidence gives no figures on how much web use was text versus other media, so "mostly" holds but may slightly understate how much photos mattered.
