I don't usually highlight a piece when I read only because I use the browser on my phone to read - as I hate the app - and it doesn't allow me to highlight the things I like within an article.

However, if I read a piece I always leave a clap or a comment or both. Even if I don't enjoy the piece I'll leave at least one clap, because I like to give credit to the writer for making the effort to create and publish their work even if it wasn't to my taste.
