And the reason we have well over 100 posts by now comes down to one
thing only: most people do not read those past 100 posts, or do not
understand what some of them say. So they keep repeating proposals that
are either not implementable in an efficient way (despite claims to the
opposite) or that do not actually solve the problem.
