My candle burns at both ends;It will not last the night;

But ah, my foes, and oh, my friends--It gives a lovely light!

Food for thought

• The interface is the application

• URLs are UI too!

• Facets aren't just for lists (with counts)

• be creative: clouds, maps, graphs, etc...

• entice users to forage and browse, facilitate serendipitous discovery
