Everything is Miscellaneous (if you define the terms broadly enough)

I'm currently reading: Everything is Miscellaneous by David Weinberger.

He says "Four new strategic principles are emerging....."

• Filter on the way out, not on the way in - put everything in & let the punters decide what/how they find and arrange.
• Put each leaf on as many branches as possible - it costs little extra, so put items in as many different categories/containers as might make sense.
• Everything is metadata and everything can be a label - see above.
• Give up control - allow others to extend metadata and therefore categorisation and findability.

Not yet half way through...

Update: Peter Morville has a few quibbles in (Not) Everything is Miscellaneous.
