Since we cover almost every little change that Google makes, why not cover this. I have been hearing reports both at WebmasterWorld and via email from Tom and on Twitter that Google is showing now a main listing with two (not one or five) indented results.
Here is one picture of what I mean:
Normally, Google will show a maximum of one indented results. More recently, Google was showing a single indented result with a plus box to five more.
I believe this double indented result is fairly new and more and more people will begin to see this.
