Angie's List Gaining Speed

Angie's List is a lot like Judy's List or Yelp however Angie's List seems to take a more serious approach to the validity of the reviews submitted.
Also I'm seeing Angie's List on a sponsored listing buying spree on various sites including Topix.net and other popular local oriented platforms. I am advising clients and friends or relatives to have their preferred clients pop into Angie's List to offer a good word or two!
