In academic research paper writing it is required to do a literature review- writing what already has been done in the field; but it is required to not plagiarism, instead write in your own words. This might be a reason why someone would run one's write up in plagiarism detector.

Being associated with research paper writing I also had an idea that the blogging would accept the same thing as do magazines. However, I later realized that social media blogging is quite different realm. It is about personal experiences and opinions. It's about originality where you need not to be statistically correct but be You. Blogging is a space where the personsl thoughts (no matter how weired) are accepted.
