Major problem I see: The name of the author is given on each article along with a brief description of their qualifications/position. This is good. Some authors have "verified" under their name, however it turns out that that only means their name has been verified, not their qualifications [1]. Some articles have references and other links to confirm things, so it's not completely unreliable, but the "verified" statement is seriously misleading. I don't care what someone's name is, I care about their qualifications. It should be made clearer that only the name has been checked.
