I recently stumbled onto a weblog called:
They solicit "nanny sightings" from around the country and ask readers to submit them for posting.
If you would like to share your nanny sighting, story or opinion, please utilize the Meebo toolbar in the sidebar to send us a private instant message, leave an anonymous submission in the form of a comment to this post or send an email to firstname.lastname@example.org. For submission guidelines, please click here.
They have a geographical index sorted by states and interesting posts about worst and best nanny experiences.
The only problem with their weblog is that the google adwords seem to trigger pop ups that are annoying. However, the content is good for parents with small children.
