in my opinion, resteem, memos and other notification is way to communicate in this platform.as a blockchain steemit has steemd which all activities and transaction noted. When we use another dapp such as esteem we get notifications about our activities in steemit.
Some time we resteem because we want to participate in a contest which ask rsteem as mandatory. the other reason is they think that the content was has good quality. I think resteem, memos and notification must be responded wisely.
Thank you @crypto.piotr
