“It let’s people share your content that you create. That’s a good thing.”

Not on a blog with ads. That’s commercial use.

It means that if someone else uses your content they have to abide by the rules set out by the license that you use. No abuse or “grey” lines here!

The line between commercial use and noncommercial use is the biggest grey line in all of the Creative Commons licenses. They’re conducting a huge survey on it now because of all the confusion. There is ambiguity between commercial use and commercial users, between profit and commercial use, etc.

It forces a “ask permission” type mentality for everything. It’s simply good practice to “ask for permission” to use stuff. It gives the author the ability to “waive” any of their above aforementioned rights on a case-by-case basis.

“Asking permission” is a good thing? The whole point of using free licensing is to avoid the legal costs and hassle of a permission culture. With CC licenses, you signal what content can and cannot be used for and ultimately limit the need for anyone to ask permission as much as possible. If “asking permission” is the norm with a CC license, that would be a bad sign.

It doesn’t “impair nor restrict the author’s moral rights.” A little ambiguous here, but good anyways.

“Moral Rights” refers to a specific part of copyright law. Moral rights don’t exist in the United States, but copyright includes moral rights in Canada and some countries in Europe.

The ShareAlike provision combats most real exploitation, while the noncommercial restriction has all sorts of unintended consequences and prevents all kinds of uses you’d actually want to allow. A NC restriction isn’t “open source” at all. Software licenses with non-commercial restrictions would fail to meet the OSI’s definition of open source.

Check out the reasons not to use NC licenses that I linked to up above.

The good think is if it's a WP blog and your on WP an automatic link (trackback – not sure of the right word) is generated. Otherwise – I try and find a trackback link. That way the referenced blog has a chance to comment and drive traffic back to there blog.

Just my amatuer 2 cents. Let's see what "human3rorr" has to says.
