I recently worked with a product also built with the Lucene search engine. It really is a remarkable and flexible tool. The ability to find something quickly and use it is arguably better than having it in an indexed list or other container. One of the interesting aspects of the product was the ability to index new information sources like a database, corporate email, any set of documents or anything else that was capable of being accessed through a digital interface.
I use Google chrome and only rarely use the bookmarks since I can search and find information faster than looking through the bookmarks.
Any system that allows one to access desired information better and faster is going to be quite useful.
