Yahoo launched a new crawler. No it's not the crab on the picture. It's the all new Yahoo Slurp.

Based on Yahoo blog, it is more efficient at visiting websites which will result in 25% reduction in the number of requests and bandwidth used by the crawler.

Yahoo also advised that we might see some shuffling of rankings on the index.

Well, if it's gonna save on bandwidth, why not. But I hope it improves my site's yahoo rankings. Last time I checked, Yahoo's search results were no that good on some of the niches I monitor.
