Content marketing is still the preferred method of most online marketers but finding things to write about is a problem for many. Even worse: having decided on a subject, you have to be able to write about it knowledgeably. The horror! We found a great post this week that brings together 12 idea-and-knowledge-generators. There are several in here that we hadn’t heard of ourselves before now.

An example:
All you need to do is enter a keyword phrase and Soovle will display keyword suggestions from up to 15 different websites. You are able to customize which sites are included, which can be useful depending on your niche. For example, Amazon and eBay are choices, so if you are in the ecommerce business, these choices make more sense for your research.

Much more here.
