Emotions play an important role when giving our vote, when reading we feel the words and phrases with which we identify in a certain way, this produces either a feeling of nostalgia or full happiness that concludes with a vote left to the post.

The same thing happens in the comments, when we read that the person who has left a very detailed comment and with the real feeling of helping, we can feel it and thank him/her with a vote.

I agree that we must freely express ourselves in steemit:)
