Currently open threads are weekly and very well received. However they tend to fill up quickly. Personally I fear that my contribution will drown unless posted early on so I tend to wait if I want to add a new top level post. Does anyone else have this impression? Someone with better coding skills than me could put this statistically by plotting the number of top level posts and total posts over time: If the curve is convex people tend to delay their posts.
So should open threads be more frequent and if so what frequency?
In other words, open threads die after about 4 days.
That's probably when people are like "I will rather wait for another open thread, so my comment has more visibility". If we will have open threads more frequently, that moment might just come sooner.
However, I am in favor of an experiment.
