If you're logged into your Google account while searching for something, you'll have noticed some changes to the results.  Specifically, arrows that allow you to move certain results up, and the ability to comment on search results.

What's my take on this?  Despite what Google is saying about how your changes won't affect other people's search results, I don't believe them!  I think that this is a cheap way for Google to have user-moderated search results!  I'm not saying the new features aren't useful, I think the changes are great but I also definitely think Google will take note of what people are doing and take some of into account.  After all, how can you ignore millions of people's opinions on where things should be ranked?  If there's a common-thread that, say, one YouTube video should be ranked higher than others for a particular keyword, Google would be stupid not to use that information to its advantage and offer better search-results.

I think it's smart and I like it.  Putting the internet back in the hands of the users is what it's all about!
