Purraise has evolved since its inception. When it was first added to the site the only option was a thumbs up and the expectation was you would only give purraise to really good to exceptional posts. You'll notice some of us that have been here since the start of it don't hand out purraise as freely as others. Now that more options have been added the purraise function is used in a similar fashion as it is on Facebook, Instagram, etc. Some of the wording on what you quoted could probably be reviewed.
