timestamps are especially important on Twitter screenshots

a) for general cultural relevance, expected audience of the tweets, size of impact b) being on the platform at all can indicate likely cultural/political affiliations in it’s earlier days and post-Elon days c) blue checkmarks can indicate a level of trust in pre-Elon tweets and no longer hold this meaning

Implications for digital archiving, use of tweets as historical sources. eg a tweet from a public figure holds more weight and more trust in 2012-2019 (estimated period).
