I finally got around to reading the coverage of what IU is doing with ChaCha and found it pretty interesting. I experimented a little with the guided search and found that they've implemented it very simply. I'm a pretty good searcher... I rely on my Firefox search bar more times in a day than I can count and have it loaded up with plenty of specific search engines. So I can't see ChaCha being my search engine of choice for general searches, but I'm really curious about it's use in specific communities like what it sounds like IU is doing. I can think of other speecific contexts where people-guided search would be really interesting. The open source communities I'm a part of would benefit tremendously from something like this where the Guides are community mavens who know the information base and people in the community really well. I'm also very curious about how we might employ something like this at rSmart to extend and streamline a service we already provide our clients as we support open source software from these communities.
