But wacky, fun, silly smileys like the ones you posted seem to be in contrast to the TMC ethos, which seems to err on the side being serious, staid, and even sterile, if i may
My perceptions about TMC are quite different to yours, maybe we frequent different threads, or it could be that different people have very different perceptual filters.
Maybe we see what we want to see, maybe we project who we are out in the world and see it reflected back to us, who knows, it is often impossible to say what the truth is as it may be relative, not absolute.
I would describe TMC as full of experts and creative folks, fun, diverse, insightful, informative, argumentative, even verbally combative, competitive(with reputation points..), civilised, hilarious, intelligent, factual, quite literate, tech-savvy, friendly,...with a healthy dose of a spicy snippiness
It would be fancy to have a snippy or a snarky icon in a library, for those snippy moments
