This is actually selling me on using emojis

People like novelty and engage on things they feel they can contribute an opinion on.

Been on many a demo in the past where all sorts of "magical" and complicated stuff is happening that ends up with "ooh I've never seen a date picker like that" or "wouldn't it be a lot better if it was blue and not red".

Often it's because they accept the other stuff is working or don't even fully remember what the demo is about.
