These look really cool as does the technology, but I don't think I've ever used Emoji past a couple of ASCII smilies. My Android handset seems to have them but I don't use them and neither does anyone else I know. Is this a cultural thing I'm missing?
Yeah, they're wildly popular with just about everyone I know 25 and under, especially on sites like Instagram. There's even been a music video created from them: http://www.youtube.com/watch?v=qmlJveN9IkI
