I want to discuss with fellow programmers a program I want to develop.

Specifically: I want to discuss if Ruby is a good choice, if it's a good idea to call the SoX command from within Ruby and parse the result in Ruby, etc.

Is there an appropriate Stack website for this? If so, which one?

Programmer Stack Exchange warns users of not posting these "discussion" questions (We prefer questions that can be answered, not just discussed.)

If Programmer Stack Exchange is the appropriate website, how should I explain the challenges I face and encourage discussion?
