Not sure what this proposal should cover. Stake pools, coding with specific Cardano ecosystem components, what else?
There are many topics relevant to cardano. When looking at existing questions, it becomes clear that those are mostly development-related, simply due to the technology related exchanges they are posted on.
When looking at other websites and communities we see that many questions are less development-related, yet still technical in nature. Due to the lower quality than on a stack exchange, these platforms are usually riddled with duplicates, bad questions and missing answers.
