User:CmdrDan/What's This?

Reviews of my user pages?
What exactly does it mean that someone has reviewed one of my user page articles?

As you can see from this screenshot, User:DragonflySixtyseven has reviewed the article User:CmdrDan/NYC Non-Profits, among others:
 * Is this a good thing?
 * Moreover, where's the review?
 * There's nothing in the revision history of the article, is there something--anything--somewhere that else I'm not seeing?
