What I learned from doc 1?

What I learned from doc was that your online appearance is everything. What you put on the internet really reflects who you are internally. People criticize and ridicule over the internet because sometimes they can say anything they want and be anonymous, or people that aren't anonymous say anything they want and get in trouble. The first impression is the best impression, so wouldn't someones first impression over the internet shouldn't it be a good one?  Also, the internet is a place where people show there ignorance.
