MAKE pal Hugh Macleod has interesting post about “prime tagging” Using multiple tags, about 20 tags would cover the 1.3 million single-use tags at Technorati. Using multiple tags, about 33 tags could give a unique identity to every person in the whole world. (Quite a few years since I studied statistics, believe I’m in the ballpark, but anybody out there who could corroborate?) And 20-30 tags are less cumbersome to navigate than 1.3 million, or 6 billion! Multiple tags can replace any single tag, however unique that is. Link.
