I don't like the #167 or #166. The icon is too big and distracting. I quite like #159 icon, though I prefer a white background and I prefer muted tones of taupe/green/grey. I also prefer the icon to the side rather than above. Thanks for your ideas!!
I like the sense of the links - kind of like a networking theme. I think the icon is a little too big though. Maybe try the oc links without the dark background around it - I really prefer the fonts of my current 1 and 2 too. Thank You!
