A try bot would help me a lot.

As others have mentioned, being able to see output from build+test is a big deal.

I understand why you want to start with a Mac bot, and I applaud starting small. However, bear in mind that lots of WebKit contributors work primarily on the Mac, so they probably won't get any use out of a Mac try bot, and you probably won't get any feedback from them until the try bot expands to cover other platforms.
