Code review post: What does the code show (ultimately do) in regards to an impression versus a view? Is an impression just about scrolling over some post for about 2 seconds or is it where the post have been scrolled over *after* 2 seconds? Also, does a view constitute a clickable or tappable action or an action that requires the user to interact with the post more than just scrolling? Thanks! @nemofin @mark @nick @medworhty @rodfather @luculent [Should this be a blog post?]
