I don’t think the people that like them are stupid. I just think the stickers themselves are a stupid concept for a messaging app - they’re large enough that they can easily push the actual text of the message off my phone screen when the keyboard is shown, which is super annoying. Maybe that’s less of an issue in Japan (and Korea? I don’t know enough about written Korean) where it takes fewer characters to express a single word. They also come across as extremely childish, at least to my North American sensibilities. I know that Japan views such things quite differently.
But if they’re as huge as you say in Korea and Japan, that would explain why Viber focuses on them so much (and why Viber keeps sending me free stickers on special occasions). And if it means that my wife gets to use Viber to call her sister in Ireland for free, instead of spending 20-30 bucks a month on cheapo calling cards? Awesome. Thankfully very few people I know use them.
