With phishing being the #1 attack vector, it definitely commands priority attention.
With passwords being the primary means of users authenticating into almost every portal, it commands that same level of attention as phishing.
I'd modify the wording of your question a little bit because "the most relevant" is not a very definitive reference. Now, if "the most relevant" were replaced with something like "in the top five", now that narrows things down considerably. In other words, I've got somewhat of a metric attached to the question.
Those questions like, "Who is the best football player in the NFL?" If that's the complete question, that's too vague, too broad! Biases and prejudices (subjective) are probably going to dominate the responses, rather than objective replies. If the question is rephrased, "Who is the best football player, in terms of total number of receptions?", now I've got a metric attached to the query, and that eliminates any subjectivity, because FACTS can't be disputed!!!!!
Whew! My short answer is up there somewhere toward the beginning of this sermon
