I logged in with Safari as well (5.1.1), and I just noticed that the subject line contains the word "Subject" and the text box contains "Your entry text..." which I don't see in Firefox.
This sounds like a bit of HTML5 enhancement! Webkit (i.e. safari and chrome) browsers (and I *think* the latest version of firefox) support displaying placeholder text as proposed in the HTML5 spec; older versions of Firefox and IE don't. It's generally thought of as one of those things that enhance the interface for users with modern browsers, but doesn't detract from the experience of older browser users. YAAY THE FUTURE OF FRONT-END DEVELOPMENT! \o/
...And this is all totally assumption; not sure if that's the page fu was on too :)
no subject
