Scott MacGregor has made the most recent Thunderbird nightly a 0.2 release candidate for reasons he has specified at MozillaZine:
Instead of calling this the August 26th weekly build, I'm going to call it a 0.2 candidate build so we can start focusing on 0.2 blockers [...]. Fortunately we had a great build last week so I think we are in much better shape going into 0.2 than we were way back in 0.1.
It's (greatly) reduced load time and various other feature enhancements/bug fixes definitely make it worth the download.
The creator of the default Firebird themes has also created a nice Firebird icon. It's easier on the eyes than the current red blotch. The Mozilla Firebird site has instructions on how to change the window icon.
Using the logo from the poster art recently created by some tech workers in Poland, ryan from brokenfall.net has created a Cafeshop featuring the moz logo on everything from t-shirts to lunchboxes. he writes:
i thought this would be a great idea to start a cafepress shop to help bring money to the different mozilla projects. i call it mozilla activism. every profit that i make through this shop will be donated to various mozilla projects.
CafePress is kind of a rip off though, but you would be the coolest indie kid ever with a Mozilla trucker hat. Personally, I'd like to see mozilla.org officially doing something like this using all the great art Shepard Fairey created (including the logo on this site, which i blatantly ripped off from the Mozilla about page).

In the Movable Type support forum, Firebird developer Ben Goodger not only notes which features will be enabled in 0.7 (support for web panels and rich-text editing—both of which are actually available in the latest nightlies) but asked if anybody out in the XUL community wants to take on designing a Movable Type template based on a quick UI spec. Anil Dash, VP at Six Apart, which produces MT, has signaled that whoever designs it gets a link from the movabletype.org front page.
