Thanks @walkingkeys for the suggestions!

Up until now, there are still little feedbacks for my posts but usually I will upvote most of them and reply to everyone of them.
Lately, I found that commenting and replying could earn me more compared to posting. Being a fresh fish here, it is indeed hard to catch anyone attention. So now, I am much focus on finding posts that I find interesting and beneficial and add value to it by giving my opinion. Surprisingly, the response was great, (just like you mentioned).

This keeps me up to hunt for more great posts and comments to join the interaction. That's the vibe I love in Steem Community.
