I've been apart of DSP stack exchange for a handful of years now and have received (and occasionally provided) useful answers to technical/academic type questions.
However, I often cut many of these "discussions" short since stack exchange websites are reserved for Q&A type dialog. I've also wanted to ask more general/open questions regarding projects and hobbies which I know don't follow the format of DSP stack exchange.
So my question here: What good websites/forums would you all suggest to have more open discussions related to DSP? For example, I've wanted to get feedback on good FPGA development platforms for learning FPGA DSP implementation but don't really know where to ask that question.
