Sorry you are having problems, but I’m not sure what you mean. I find things pretty clear with this new design. Can’t you tell visually where to type text? When you typed your message above, wasn’t ti clear that there was a big white box to type in? I haven’t tried tabbing around the pages, though, so are you basically saying there’s not good support for :focus? The :focus styles are a bit faint, but they are there.
for what it’s worth, i’ve got the same problem (using IE8), but i’ve learned approximately where to click with the mouse in order to find the input box, which is for all intents and porpoises invisible
