File this under "It's about time." Google has promised its new Caffeine search engine will be faster and more relevant. Why are they announcing this now? Probably because Microsoft's Bing must look pretty good to them. Nothing like a little competition to scare the complacent. While Google has gotten better at filtering out dreck, bargain travel sites, and link farm spam in the past couple of years, the search engine still coughs up way too many results that are not especially useful or relevant. Does anyone ever look past the second page of search results? In my experience, the relevant links disappear pretty fast after page two or three, but Google still seems to think returning 50,000 links is a good idea.
