..Maybe they have to be preachy, since they keep the videos so short? Consider this, Preaching means inclined by tedious moralization, So they get what they mention the topic, the moral dilemma it brings up, how to change it or notice it or why it is....then end the video. It sort of makes them seem preachy because they can't or won't cover every thing and they condense it down to basically nothing. It should get better when they cover all the HUGE topical gaps they've created for themselves. So as the library gets bigger, the less preachy they should seem.
