Just yesterday I ran across this example: "(っ˘▽˘)っ :cloud: ⊂(◕。◕⊂)" in the Parse SDK repo, which I found especially distracting, and in general, kind of turned me off from the project (even though I know Parse is awesome).

This reasoning turns me off from types who have it.

It's not like they use emoticons everywhere -- and if having one is the big distraction one can complaint about, then their repo is in excellent shape.
