My goal is it, to provide an innovation blog. Each registered user can write about an innovation he found. So there have to be "Comment" functions and functions like the "Like" Button in Facebook on each blog.
The Blog entries should be ranked concerning their "Likes". Besides the Blog entries, there should be more "tabs" for background information, such as "about us" or "Channel". In this "Channel" Tab, the blog entries should be sorted by topic (e.g. "renewable energy", "technology", science", "IT" and so on). The user writing a blog adds himself a tag to his blog entry (e.g. "technology").
