Demand Studios has been known to copy ideas before, and their latest idea, eHow Spark, is no different.
Spark works a lot like Pinterest. You can pin photos and text to your boards and share them with others using an app or a "clipping" tool.
The catch is, while Pinterest says in their Terms of Agreement that they have no claim to what is pinned on their site, eHow claims everything:
|Click on it to make it larger.|
I think this is a clear warning to content producers to stay clear of this site. If you want to keep other people from using your content on eHow Spark, head on over to Crunchy Data to get some code to block the clipping tool.
