First of all, I absolutely loathe emojis and hate that they are on by default with no (easy) way to disable (turn into flat glyphs in the color of the text, not :some_stupid_name: as some applications offer). It makes almost everything look ugly.
Having dozens of sets of emojis that look quite different doesn't help either (on web in particular). And there's not that much coherence within the sets either. Apple in particular is really bad at this. For example, beer looks like a photo, whereas crap is in a completely different style. Each individual one can be nice and well thought out, but it makes them all look bad if they don't fit together.
(Twitter's are much better)
Must be an incredible feeling to have designed and drawn what is fast becoming a core part of our language.
Although looks like the pile of poo and ice cream no longer use the same swirl:

I'm missing two smiley icons:
-big hypocritical smile
And I'm missing the option to create and send my own emoticons as SVG.
