Collaboration on the web is an area of exponential growth. Crowdfunding, or collaborative funding via the web, is one of the standouts for growth in this evolving collaborative economy. There are 2 main models or types of crowdfunding. The first is what's called donation-based funding. The second and more recent model is investment crowdfunding. Business owners are using different crowdfunding sites than musicians. Musicians are using different sites from causes and charities. Below is a list of crowdfunding sites that have different models and focuses. 1. Kickstarter -- is a site where creative projects raise donation-based funding. These projects can range from new creative products, like an art installation ... to pre-selling a music album. It's not for businesses, causes, charities, or personal financing needs. 2.
