I don't think it does really. Sites like leanstack.io exist but are not the same thing, they just provide lists of tools without the great context and human contact that usesthis has. Other sites have long interviews with founders without too much emphasis on the tools used.
I am currently adapting the usesthis approach to an idea that I have and would be very interested in chatting with you, or anybody else who's interested, to brainstorm on how to proceed with your idea.
We've actually have more detailed posts now (i.e. http://blog.leanstack.io/the-cloud-stack-that-helped-sendgri...). But I'm with you on context, we're going the interview route moving forward. Glad to chat with you and anyone else to brainstorm and see how I can be helpful though. Feel free to email me at yonas@leanstack.io.
