The Internet is an invaluable source of information -- but not all information is created equal. It's important to realize that some things you find online that support your argument or agree with your beliefs simply aren't true, and some things that you vehemently dislike are, in fact, accurate.

Reliability: Are they using their citations accurately

Purpose/Point-of-View: Is this opinion, research, or journalism? What bias is present? Are they trying to sell you something?
