Credibility & Sourcing
By definition, Reddit is a forum that is completely open to the public, and as a result, a lot of the claims made on the site can be difficult to verify and validate. This is not to say that there aren't worthwhile, source-backed posts to be found here, but rather that a stricter sense of fact-checking could be enforced. With this being said, Reddit's modus operandi is at complete odds with the concept of sourcing. The expected house rules are present, but in this realm, it pays to sift.
