Maybe fallout from the downtime? Don't see my quick-edit pencil on my blog when I'm logged in, and don't see the left & right arrows to navigate the "blogs of note" on the blogger login page either. Was there an icon day-trip scheduled for today that no-one told me about?
A lot of the blogs I work with those icons don't display... the link is still there, but you have to know where and position your mouse over the correct spot, even though there's no icon
I think some Googlegeek must have tripped over a serial cable or something.
