I got tripped up by the placeholder text in the Edit Summary, so I am wondering what do other people think about it?
When I clicked into the Edit Summary text field, the cursor was not at the beginning, it was in the placeholder text where I clicked. This made me think I had to delete the placeholder text, which I did. It took me a few go's to realize it disappeared when I typed.
Some alternatives I can think of are:
A) An alternative is to remove the placeholder text when you click. This is the behavior of using the HTML5 placeholder attribute and browsing in chrome
<input type="text" value="" placeholder="Search by city, postcode or address" name="q" id="search">
B) Move the cursor to the beginning of the textbox no matter where you click, or if you press the right arrow. Make it appear that the textbox is empty
C) Put a label behind the input box with the placeholder text in the label. Then clear the label when you start typing. I have never tried this option, but I assume it is possible.
