It might be better to say just more than "Thank you" to reap real rewards from the Steemian community. As I understand it, you get rewarded if a Steemian upvotes your "Thank you". In the absence of an upvote then I don't agree to: "Steemit, the only platform that pays you when you say "Thank you"". I stand to be corrected.

You might want to consider using this Chrome Plug in, SteemPlus.
