These minor issues have existed since ES 1.2 beta, but finally figured I'd voice them.
1. When you hover over your profile picture it says "javascript:void(0);" in the url below, but shows nothing when hovering over the cover. This is inconsistent. Personally I prefer the non js display better.
2. When hovering over your profile photo it shows your cursor as a pointer, it displays as a basic cursor over the cover. In this instance the profile photo does it right, displaying the cursor as a pointer indicates that clicking will open something.
3. Cover uses css background while profile image uses img tag. I personally prefer image tags myself. This is a minor issue, perhaps it's a lot easier to work with backgrounds for cover positioning? Figured I'd bring it up considering that we are talking about differences.
