If everybody used this thing, it might make Divester obsolete, but I thought it was worth mentioning anyway. After all, you survived BEFORE Divester.

DiveGoogle is a search engine that searches "top scuba diving websites" and returns only scuba diving-related terms. (In other words, you'll no longer type in "diving," and get results about baseball players "diving" for balls in left field.) Working by automatically visiting a database of key websites and registering all the keywords and potential search queries within those sites, the goal of DiveGoogle is to allow websites to compete "based on their key relevance and not based on their link popularity like Google." In theory, of course, it sounds like a cool idea. What's the downside? Well, DiveGoogle will not index websites without its creators' authorization, and to get into the system, it'll cost you $250 a year. Consequently, it may not be as pure and objective as Google allegedly is. Cleverly, though, the team behind DiveGoogle has also developed the DiveToolBar, the first Browser Toolbar aimed at scuba divers, which is free for you to download.
