Earn: It is proper netiquette to give likes to deserving content.
Earned Engagement Deserves Likes
Likes are earned for good reason. It’s alright to encourage friends to curate and create better content if you think it will help them post something you like. My friends only like high quality status updates. If they don’t like something at first I rewrite it until they do or find something new to post.
Work For It
Most people don’t Like everything they read. The decision that a message, article, or blog post is good requires a certain level of understanding of it, good writing. Good writing takes practice, proof reading and persistence. When users Like good writing they give credit for hard work.
