I think because we are making the installation process easier and easier, there are less and less questions about the system itself (which was the original purpose of the Discord). Our goal is to develop this Discord into discussing all kinds of technical related challenges and discussions such as the TimescaleDB discussion we had a couple of days ago in a thread. All other KPIs (such as newsletters registrations, website visits, clicks coming from google, etc.) are continiously rising, so we are quite confident that it will change over time.
To engage further in the discord channel, we are currently doing office hours (which are only available here), we are publishing more content and also content in here earlier than on LinkedIn (to bring the discussions on linkedin into the discord). If you have any other ideas, feel free to write us!
