Blogs vs. Regular Websites

From what little I know about blogs, I've always assumed they are like online journals--people write what they're thinking and post it for others to read. Regular websites, on the other hand, are the go-to information sites. It's where we find the weather, learn celebrity gossip, catch up with our favorite sports teams, where we find information, etc. Websites are (usually) professionally designed, updated frequently, and are intended to reach out to a number of different audiences. Blogs (again, from what I'm assuming) tend to be updated less frequently, are less intricately designed, and may even be less accurate and or/less popular than other websites. Not sure if that's the answer to the question... but I thought I'd give it a shot.
