Gnoos is a new blog search engine, launched yesterday. It is focused on indexing Australian blogs as well as bloggers with a “global voice”.  Each results (a blog post) can be commented & rated at Gnoos. Total votes for a post are counted and, soon, will be used to determine relevance in later searches. Clicking on the “more” button pulls up the entire post. This seems like an obvious feature. Finally, tags can be added to a post on the fly in a box below the summary.
