Online Communities - The Nest

Product Name: thenest.com

Why it's great: This site is a great community for "smart women". It's targeted at newlyweds, but really the topics addressed are relevant for all women. I'm a big fan of the message boards, and frequent my local community as well as the ones focused on work and money.

How it makes you more efficient:
1) It's a quick way to get answers to your questions - whether it be a restaurant recommendation or a tough issue with your husband.
