YEAH! I saw the new favicon and did a double take... I don't know how I feel about it... I like liked the old one better... this one looks like the infinity sign sideways :/
Why does the favicon really matter besides how it looks in your bookmarks? They could have a favicon of a smiley face and it really wouldn't change anything.
I noticed it on Adsense before I put in account information. I thought my page had been hijacked and someone was looking to steal a password. Relieved to know it was just a favicon change.
