I agree with your opinion about social media, especially in the last paragraph. Social media is the most important way for many vulnerable groups to obtain information. Social media can help them provide some resources and information and help them learn more skills, so social media must be regulated to keep its fairness. Your definition of some software is also good, such as Brightspace and Coursespsce. But I have a question about the content of your second paragraph, which software do you think is the most meets the theme of an academic platform? Overall, your article is well written, such as the advantages and disadvantages of Chegg, and the academic authenticity of social media like Youtube. I look forward to your next blog.
