Hello SO,
I think almost everybody know or heard about what I call the yes/no notation system: thumb up or thumb down. Youtube uses it at the moment.
Education uses a ABCDEF grade notation. It doesn't really apply to web, I'm looking for methods that can be used for articles tips, or videos.
Another notation system relies on stars. Up to five in general. This is the old youtube system. I think the stars really got into people to mean an evaluation about something.
Still, youtube switched from stars to a like/dislike system. Is that a better notation method?
What other system do you know? Links to resources and articles appreciated.
Thank you!
