This article tells us Donald Trump's Twitter posts are not just written by himself, these posts are posted by iPhone and Android phone. And data shows that the posts published by Android phone are written with angrier and more negative tone, which are written by Donald Trump himself. The other half posts are published by staff who are trying to imitate Donald Trump's tone and publish positive views. The article tells us the authenticity and inauthenticity on social media. So we should be able to distinguish what we can trust and what we cannot trust.

Just like this chapter says, parasocial relationship is very common on social media. Such as influencers and their followers. In Chinese TikTok, the most common way that influencers call their followers is families and brothers no matter they are male or female. This kind of call builds a parasocial relationship between the influencers and their followers by giving followers a illusion that they have a very close relationship with the influencers, so they would be willing to buy the merchandises the influencers are selling. I also followed some influencers such as fitness bloggers and they replied my messages sometimes, but when I asked them work out together face to face, they would reject me. So parasocial relationship is authentic in the way of giving the followers emotional value and support, but it is also inauthentic because influencers are not friends with most of their followers in real life, but they still act that way.

This article shows the history of how black people were looking for a platform to express themselves, communicating with other black people, and spreading their culture to the society. They tried Facebook and some other platforms and finally realized that twitter is a platform that had more freedom and fun. From this article, I felt the power of social media. It brings people together and pushes the development of society and culture.

With the internet and social media development, various kinds of platforms and apps start to emerge. By reading through this unit, I'm so glad to see and feel the development of social media, which made the communication between people so easy and convenient. Meanwhile, So many bad information starts to appear on the internet. This is an uncontrollable thing. So all we can do is filtrate the information from the internet and choose what is beneficial for us.

This article is about Elon's query of the percentage of fake accounts and his plan of buying Twitter. Currently, twitter is already under the name of Elon Musk, but the question about the fake accounts on social media is still a worth-considering question. Data on the internet is simplified and it comes with some bad impacts, so when using internet, we should be able to realize what is real and what is fake. And when we post data on the internet, we should try to use the most helpful way to represent the reality we want to show to others.

I totally agree with this. All data is a simplification of reality, but in the process of simplification, some information is lost. So when we are choosing the way of simplification, we should consider the pros and cons, then decide which simplification would be the best to satisfy the need of different users.

This is a really common thing happened on the internet. Even though some information are not true, people use bots to send so many likes to these information, in order to lead others to trust these information because they are being accepted to so many people. Bots can also bring many fake followers to accounts to make them look like authorized.

This article is about how people use clicking farms to bring flows to a post or news on social media. It makes posts and news look like being more popular so people will follow the "fake" popularity. So nowadays, there are so many informations on the internet that are being popular artificially. It feels like we can only know things that others want us to know.

I don't really agree with this point. Parents get the right to be treated or not, but as a sad thing, instead of completely ignoring the illness, we should at least try to convince them to do so.

I really like this sentence. No matter what thing are you focusing on, all you need to do is try your best. Don't be worried because of anything that you cannot decide.
