Thanks for your work on cl-async/blackbird: we also used it in our recent project (and you should have gotten a couple of related requests)! I don't think you should be discouraged though: your contribution is very valuable and surely was noted, just that the whole async approach is, in my view, not in line with the general direction of where Lisp is most applicable, currently (we should admit that it's a niche language). After all, having an evented server means that it doesn't perform a lot of useful computations, most of the work is just serving some kind of existing content. I.e. you could say that the application logic is marginalized and commoditized. And Lisp is the best choice for the opposite cases, those that require and emphasize elaborate application logic and intense computation...
