It has got a really positive response and we've already got very good questions and ideas for using it in ways that we didn't expect. Thanks all!
I have to step away from leading the project as my backlog of devrel tasks essentially grows by the day, but I leave node-firefox in the capable hands of my colleagues .DS_Storoz (also known as Brittany Storoz) and tofumatt (also known as tofumatt). Of course I'll still be hovering around the project and maybe building the occasional module and whatnot! You can't get rid of me that easily... ;-)
