Instant Search Hacks
The Instantise website features Hacker News Instant, PHP.net Instant, Twitter Instant and Images Instant. With the proliferation of third-party hacks to make current search features "instantized," it's clear that in the world of search, nothing is ever fast enough.
Implications - The creator of the Instantise website is Tam Denholm, who hilariously quotes that his idea was "inspired/stolen from Michael Hart who got inspired/stole from Feross Aboukhadijeh who got inspired/stole from Google and boredom." It is pretty interesting that you can have so much information converge to one place on the web.
