Telegram does not provide ways to obtain data about one’s audience and understand how this data differs from a priori assumptions. So, as a workaround, I am using my favorite method—a survey. How will I apply the knowledge that, for example, my main audience consists of thousand-year-old grandmothers? Hell if I know; maybe I’ll pay more attention to texts about the design of benches and entryways, as well as the differences between a drug addict and a prostitute.
