Web data mining made easy

Man, and I just complained about Spock which is nothing in comparison to this: If you need an efficient tool for collecting and connection web data about people, organizations etc. then Paterva's Evolution is the answer for you ... but hey, why do you need such a thing?!?. I stumbled across it via a good article on Linux.com. Evolution offers a (closed-source) java-based GUI and two web interfaces (only the classic works at the moment, the web-wizzard cannot be used currently). It is a little bit slow but considering the amount of sources it harvests and the results you get it is pretty okay. I am fascinated and scared on the same time. That just makes it too easy.
