The rise of the open source design movement has seen a slow but steady rise in the community of open source designers. Some sites offer open source templates in addition to other content. According to etemplateshub.com, as of this writing there are over 4000 unique HTML website templates available for modification and use by anyone under various open source licenses.
Yeah, and as a developer, I really appreciate the fact that I can go and shop around for a free design, modify it to my liking and launch a site very quickly. Saves me TONS of time.
