I will review findings from our recent studies regarding design guidelines for chatbots and about work practices of professional developers and curators. Most of the results were obtained in the context of customer service chatbots, but I will discuss which ones may be valid for other domains, such as entertainment bots and professional conversational assistants. I will also discuss bot development as a highly collaborative practice which tends to be poorly supported by the current tools and platforms. Based on some concrete case studies, I will make suggestions on how to better support developers and curators.
