Details: Nichecrowd offers a quick-and-dirty way to talk directly with any group of people @nichecrowd allows you to talk directly to any group of people. The method is very low-tech: simply describe your target audience in your post, no matter how specific, and visitors will decide themselves if they want to read what you wrote. Posting these email-like messages works on a freemium model: it’s free to post a message, but it costs money to display it near the top.
