Voted for

• The author himself/herself (if you know him/her)
• The title of the post
• The image of the post

The author's reputation is not matter for me, as long as it is 25 or more.
If it is below 25, then there is a high chance that the author is a spammer and/or a plagiarist, and thus the low reputation is become a trigger to not to read the author's posts.
If a user have low reputation, then the contents of his/her posts also become hidden by default.
The author himself/herself is not a priority, because my main goal in going to the new section is to find/discover new and interesting people with interesting posts, who/which are unknown to me.
But it can still be a trigger, so I voted for it.
The title (and the topic) of the post is obvious.
If it is interesting, then I am going to read it.
Probably these (and the image of the post) are the main triggers to read a post from new.
Maybe the image of the post is grabbing my attention before the title of the post, but the main trigger for me to read a post from new is the title (and the topic) of the post.
