Metadata is information about some data. So we often think about a dataset as consisting of the main pieces of data (whatever those are in a specific situation), and whatever other information we have about that data (metadata). For example: If we think of a tweet’s contents (text and photos) as the main data of a tweet, then additional information such as the user, time, and responses would be considered metadata. If we download information about a set of tweets (text, user, time, etc.) to analyze later, we might consider that set of information as the main data, and our metadata might be information about our download process, such as when we collected the tweet information, which search term we used to find it, etc.
One question I had in this section is whether metadata can affect people more strongly than the post itself. If someone sees a lot of likes or a blue checkmark first, will they trust the post more before they even read it carefully? This made me wonder how much our opinions on social media are shaped by the content, and how much they are shaped by the extra information around it.
