Google is getting more relevant

It seems that Google is getting more and more relevant for information searches. I'm guessing that they use the data that people enter into Google to refine their queries. For example, I searched for Poseidon UML (a UML drawing tool) and it came up with the correct page. But more importantly it had direct links to things which most users may want for such a query. Downloads, Screenshots, Support...are all things that would most probably be entered next into Google in the past when such a feature was not available.
