Since Google rolled out Google Instant, there has been an explosion of search mashups created by enterprising developers. First there was YouTube Instant, for which the creator was offered a job at Google. Next came iTunes Instant, which lets you quickly search the iTunes store for music, netting the 15-year-old developer a 5% commission if you buy anything. (I was kicking myself for not thinking of that first…)
There is also an App Store Instant and Instantise, a collection of various instant searches…
Since everyone else is making instant searches, I took an hour or so of my time and whipped-up an Instant Twitter Search for the fun of it.
