I recommend Creative Commons to almost everyone I meet and actively discourage people from creating their own licenses.
However, this doesn’t mean that CC is for everyone. Not everyone who posts their work online is a good candidate for CC nor should they use it. Not only can it hurt your livelihood, but using it incorrectly might also damage the Creative Commons cause by letting people walk away with an unwarranted negative impression of the licenses.
This is why, before putting the CC logo on your site and announcing your new terms, it is important to take a minute and ask yourself if it is really right for you.
Having the skill to use open licensing effectively is a big part of succeeding. Different licenses have different impacts. Depending on what you’re trying to accomplish and what the market wants, your choice of license can sink your project or help it take off.
