Okay, thanks for digging into this but let me clarify:
I feel like the OP is perhaps being restated as a strange all-or-nothing campaign against writing smiles. This is not the case though is easy to have happen in a forum setting.
This is in "Hints and Tips" because I'm mentioning something that, when it is done badly, makes for weak and awkward writing. The article that I've linked to in the OP did a pretty good job of explaining some ways to improve.
