Hot and Marginal: like hurricane on the US south, Trump elected as president, and book-club discussion. Sudden burst of interest as they may be, the span of attention is short, and soon taken over, if not forgotten.
Perpetual: like Climate Change (CC), pandemic, God as Creator, and democracy. They endure and persist with the serious concern of the public, philosophically and mentally.
This Forum makes no difference between the two. Every New Topic will be put on the top of the chart, to drop an earlier topic from the table-top. Topics, important or trivial, will all last for a week or less. Exception to this rule can be found. Some 4 topics here as raised by Scott, for example, stay permanently on the top, which makes sense. The implication? Probably that prioritization is sometimes necessary.
It is about time to introduce Reform. Establish a list of say not more than ten Perpetual Topics which can be reviewed from time to time, to attract new and old audience and commentators. If someone has some burst of thought on CC, for example, he can then be served with the convenience of a ready forum rather than to start a new thread. For me, I would certainly check the forum more often.
