Let me start this by saying almost every brand/advertiser/sponsor at BlogHer '09 did an outstanding job of connecting with the women at the conference.
But there was one brand that stumbled - Nikon. At their invitation only event, they turned away moms who brought their babies. The reason was apparently that the restaurant where the event was being held had a 'No babies" policy.
This is a classic case of "the devil is in the details."
