We conclude that symmetric SNSs facilitate more interactions, potentially providing a more effective platform for peer-to-peer corrective feedback compared to asymmetric SNSs. In the long-term setting (not in the short-term setting), a moderate positive correlation was found between the number of characters and the number of grammar errors for Facebook, but not for Twitter. There were more grammatical errors on Facebook than on Twitter in both settings. analysis of networks patterns (Martinez 1991) it is there. More interestingly, Facebook appeared to be a more dynamic system the quality of writing seemed to change over time. Asymmetric specialization is present in plant-herbivore networks even if it appears less. Facebook also displayed evidence on promoting explicit corrective feedback.
