Well in this case the reason you got so much for the comment was one of the voters is a whale. She happened to be commenting on the post too and liked what you had to say :) Well thought out comments on a post with a lot of activity, particularly when you catch the post early, are more likely to earn you comment upvotes.
I would be careful about asking people how to play the game. It makes you appear disingenuine. All I can tell you is that the comment you initially wrote was a good one. I don't mind that you asked me to visit your page, but I should also warn you that many people will. Basic rules here are: Be sure to always upvote a post that you comment on, make sure the comment is a thoughtful one that lets the blogger know that you actually read/watched the article. Never put a link of yours on someone's page unless you're friendly enough with them that you know they won't mind, or they happen to be in the post that you made. Don't ask people to follow or upvote you.
But really the most important thing is to be genuine and develop real friendships. Chasing whales will get you nowhere. Be positive, that's always welcome.
