Not very correct. Need to add an 'valid' flag.
isNewer() and isOlder() are both implemented which is confusing.
But they are both needed.
Rename isOlder() to isWorthlesser() bzw. findMostWorthless();
Rename isOlder() to isLessRelevant() bzw. findMostIrrelevant();

isLessRelevant()
isMoreRelevant()
findLessRelevant()
findMostRelevant()
