The degeneration is spreading inevitably like orbit trash, but at a rate a thousand times more. Opposite the Earth's orbit, in the Web, some sub space could be guarded from this occasional degeneration. Many patterns that are not of Nostradamus' type already in the total Web, could be made Nostradamus patterns in a Web sub space, specially intended for idea search. Search etiquette, expecting that everybody announcing an idea, adds to the site several Nostradamus-type word patterns identifying the idea, with links to more detailed information, and tries to not degenerate the space. A similar etiquette has already come into action about announcing sites to worldwide searching utilities.
Nobody is obliged to do that, but everybody does.
That is just an implicit collective agreement. The same practice is possible for target idea management. I spent just a minute for the checking. That is the way it should be for a huge amount of little and large ideas identifiable by word patterns. The first idea banks and idea searching tools have already appeared on the Web.
