"The changes you make only affect your own searches. But SearchWiki also is a great way to share your insights with other searchers. You can see how the community has collectively edited the search results by clicking on the "See all notes for this SearchWiki" link."

I could see this aggragating into effecting search results at some point down the road. In the meantime, commenting on the choices does seem to reach other people, and possibly google itself if enough people are asking why the official ISM doesn't show up for its own name.

Meanwhile, I'd be interested in hearing more about how this sort of thing can suddenly take place.
