The post discusses an innovative project, Erlang-RED, which aims to bring visual flow-based programming similar to Node-RED to Erlang. The developer seeks feedback and has identified several aspects that require clarification, such as defining flow-based programming, the target audience for this tool, and the integration of operators. They emphasize Erlang's strengths in concurrency and low overhead processes but call for improved documentation for non-technical users. The community has provided suggestions for enhancing user engagement, like videos or examples, and raised questions about the tool's usability and similar projects in other programming languages. Some users express a desire for a DSL focused on event-driven programming, indicating a niche interest in such technology, along with concerns about the challenges of managing large, complex programs in flow-based environments.
