Funnily enough Dave recently asked me if I might be interested in writing a book and although I can’t think of a topic that I’d want to write about right now I’ve just sent him some brief details of the idea I mentioned above. I’m not sure if it’s something that will tie into PragProg’s plans but if it is I definitely think you’d be a great person to trial it with first 
I’m also going to add your book to my to-read list as I’m always interested in fast and scalable systems 
(no promises when I’ll get around to it tho, my list is pretty long atm - hopefully I’ll get a bit more time once the winter starts to draw in).
Thanks also for mentioning Devtalk on your new website - please feel free to use our logo if you need to
