Blogs vs. Wikis

As I continue with my collaborative experiment eCube, I am attempting to integrate and popularize the organization Wiki. I am finding working with Wiki much harder than working with a Blog. I find Wikis more complex and less user-friendly, which sort of defeats the purpose I guess. With my blog, I find I have more control over what I want, how I want the content to appear, and linking other content in my blog. Wiki seems to present me complex codes to create a meaningful page. While I guess once I learn the ropes of Wikis I will be able to make the most of it, but for now the learning curve of the Wiki is much steeper. My worry is that my usage of Wiki will be limited to reading and not contributing.

Is it just me or are Wikis actually harder to learn than Blogs?
