If you look in the address bar of your browser you will see a blue square with "Co" in it.
Unlike the rest of this website, the logo feels a bit... slapped together.
I think we all need to think of a new one.
Ideas:
Put the Co on a keyboard key
Put a ) rotated 90o clockwise to below it to make it look like a cute smiley face.
I know that sounds stupid, but everything about this site has a very human feel to it. The smiley face, while seeming unprofessional, is very personal. Sometimes, that is the idea that you want to convey.
These two combined:
Put a border around the Co, but emphasis the bottom portion of the button's border in a way that it looks both similar to the key and the letters, so it looks like both a keyboard key AND a smiley face! This would tell the users what its about (for their bookmarks) AND give that human feeling.
