Publishing online is easy. It's even easier for others to copy your work. There are many reasons why you might want others to copy your work. It can enhance the popularity of your blog, raise your personal reputation in a community, and even make a few dollars for you if you host advertisements on your site. There are also reasons why you don't want to allow others to copy your work. Plagiarism of your entire site or republication of an entire entry may confuse readers and lower your traffic. Lisensa helps solve both issues. By making it easy to select a Creative Commons license, you can allow non-commercial users to copy your work under terms you select.
Lisensa is not set up or aimed to help find splogs and other copyright infringers, for this you can see Copyscape and the upcoming Sentinel for help. Rather, like BlogBurst, Lisensa will help bloggers syndicate out their content, with or without a fee, to third parties who would like to use it legally.
