Of all the smiley's the borg and the cylon are cool..
The other ones.. like the normal smiley, just I find and I'm sure it's pretty much only me.. but I find them a bit over done.. the smile is just a bit to big, the eyes a bit to round.. and instead of the *Smile* that I would think.. it almost always rubs me the wrong way.. so I deliberately pretend to not notice them. And pay attention to their intent.
And it's funny other smiley faces don't bother me at all... these here for a lot of them just almost grate on my eyes.
So I'll stick with the Cylon's they are ever cool, and their smile is always pleasant to my eye. Hehe.
(Though this one, makes me smile.. it's friendlier!)
