Hello!

I am new to the Wikipedia community!I need your help with editing

I have added this paragraph :

Critics of social media such as Keen (2007) were concerned with the use of applications such as Instagram, because they thought the behaviours portrayed on these sites could potentially be linked to the narcissism trait. In his book, The Cult Of the Amateur, keen argues that “Self” is running digital culture, and he is of the opinion that people use social-media platforms because they are interested in advertising themselves. Buffardi and Campel (2008) also alleged that Instagram offers “a gateway for self-promotion via self-descriptions, vanity via photos, and a large amount of shallow relationships” However, Buffardi and Campell (2008) later said that the large number of users suggests the general psychology of the members is normative.
