SHODAN will definitely motivate network and server administrators to stay up to date with the latest vulnerabilities. It could possibly even be used by them to test to see if their servers are vulnerable. Overall I don't think that will have an overly negative effect. Instead, like any other dangerous tool, it will cause people to find a way to limit the danger that it poses, and that means that they will work harder to make sure that their servers are up to date and as secure as possible.
