Diigo seems to work quite handily, but I still prefer Delicious and will mourn its passing. It's easy to export your Delicious bookmarks to an html file and import that into Diigo.

A single seed bank like this doesn't make any kind of biological sense. It is remarkably unlikely to be useful in the event of catastrophe: it's a long old road up there to Norway to replenish stocks of some ancient carrot variety from most parts of Europe.

If you actually wanted to guard biodiversity, you would encourage social networks of gardeners to replant varieties each season and share the ensuing seeds. The French organisation Kokopelli does this, but seems to suffer from legal harassment rather than incur the subsidies it would receive in any sane world.

An analogy for the slashdot crowd might be Napster (centralised) vs. BitTorrent (distributed).

that moldy alfafa will have made really nice mulch/compost for growing veg. Your old computers on the other hand are destined to pollute a water table somewhere.
