The VirusList ran by Kaspersky now has a new look. Easy on the eyes and much easier to use. Even more interesting. Is the fact that Kaspersky is now running a blog off that site as well. This definitely shows that the power of the blog has been seen in my opinion. Granted other very well known companies have blogs as well.
