I think this my friend is more a question of your status inside the community. For example user with a high reputation gets in most of the times more upvotes then someone with a lower rep.

It's also a question of visibility.
Those people are known in the community but newcomers need to hustle their way up.

In know from myself. In the beginning the post you shared don't get much attention.

Keep on steemin and. Connect with others here, work on your reputation and you will see a diffference :)
