Yahoo! Search Blog announced that AllTheWeb is the first of the Yahoo! owned search properties to test out a new search technology called Livesearch. Livesearch is similar to Yahoo! Instant Search in that it shows results as you type, but it also "related queries, spelling suggestions, and enables you to use keyboard shortcuts to help you find the right query faster to get to the results that you want." Let me tell you, it feels incredibly quick and sleek.
Only issue, I went to it on Apple Safari and saw this message.
For an optimal Livesearch experience, we only support the following browsers with javascript at this time: Windows 98/2000/XP - IE 6.0, Firefox 1.5 Mac OSX 10.3 - Firefox 1.5 Mac OSX 10.4 - Firefox 1.5 We plan to support Safari soon. Please let us know if there is interest. Sorry for the inconvenience.
Yahoo!, yes there is interest.
