It is not designed, and will never be a place to foster discussions, or encourage exploration. I'm NOT complaining about SO, this is just how it is designed.
This kind of content, for example, is not something SO would create:

https://github.com/skx/static-site-generators
Since we don't have a SO for discussions we still rely on information from individual research and/or the modern-day newsgroup (reddit, forums). I wish there was a place to fully explore nebulous unanswerable questions like "Which web UI framework is fastest to develop in?" or "What is the best way to start a 2d platform game today (in 2013)?"
This isn't an easy problem to solve, the questions above aren't really there to get an answer but to start a discussion. For both questions I want to know what is popular (TODAY, not in 2006), active, has been tested, and personal experience. I want to see a collection of people submitting their own takes until a top-five is produced where further study can be made.
