According to Jih-Hsin Tang, Cheng-Chung Wang, bloggers tend to have significantly different patterns of self-disclosure for different target audiences. The online survey which involved 1027 Taiwanese bloggers examined the depth and breath of what bloggers disclosed to the online audience, best friend and parents as well as nine topics they revealed. Tang and Wang (2012), based on their research study on the relationship between the social penetration theory and blogging, discovered that "bloggers disclose their thoughts, feelings, and experiences to their best friends in the real world the deepest and widest, rather than to their parents and online audiences. Bloggers seem to express their personal interests and experiences in a wide range of topics online to document their lives or to maintain their online social networks." As we can see, blogging is another medium that we can use to understand social penetration theory in today's world. Regarding online chat, research conducted by Dietz-Uhler, Bishop Clark and Howard shows that "once a norm of self-disclosure forms, it is reinforced by statements supportive of self-disclosures but not of non-self disclosures".
