If you’re a signed in user of Google, you’ll notice the most significant change in search since their launch.

You can now interact with search results, wiki style.

You can vote them up or down and leave comments. And they will be seen by others.

1. This is going to lead to an incredible rush by small businesses and social networkers. They’re going to go crazy trying to game the system.

2. Google is going to find that millions of people pay a lot more attention to their search results (for now).

Interesting to consider what happens after that. How do they handle the deluge? Does democracy matter when it comes to search? How do you filter out the gamed votes?

Also interesting to think about how a tiny change in a beloved interface changes the way you think about and use it.

Google is a natural resource. We’re defensive. We don’t want them to wreck it, we want it to be here forever and we want it to work better for us. All at the same time. I give them ten points for bravery.
