What shape of avatars for members?

I really prefer a square with rounded edges (border-radius 10px or so).
However, sometimes a circle image also looks good like on YouTube.
I have not seen many octagons around, and certainly no triangles lol!

I prefer circular avatars but don't have a problem with square. I have not seen any other shapes anywhere.
