Great Nonprofits is a website that those with an interest in non-profits will find most useful. Great Nonprofits describes itself as the Zagats, Trip Advisor, or Epinions of the nonprofit world, as it encourages the employees, volunteers, and donors of charitable organizations to give reviews of them. There is a tab in the menu at the top of the page entitled "Find Reviews", where visitors can search for nonprofits by "Name", "Location", "Highest Ratings", "Most Reviewed", and "Most Recently Reviewed". Visitors can also browse using keywords, such as "arts", "environment", "mentoring", and "youth". Many of the reviews are by those who were drawn to the organization because they needed help from them, such as a reviewer of the American Bladder Cancer Society and Earl's Place, a support organization for homeless men. Visitors can "Write a Review" of a nonprofit that is already in the directory of almost 5500 organizations, or add their own listing for a new nonprofit. At the bottom of the homepage, interested visitors can also subscribe to an e-mail of "biweekly tips on volunteering, giving and innovation in nonprofits."
