Creative Review is a design magazine that I have subscribed to for a while. They have a blog and currently are holding debate about whether or not to blog.

I would like to use my blog for news posts and visual case studies for work that I am currently doing. I think each individuals blog has to be used to communicate whatever that individual enjoys doing otherwise as I have found it gets put to the back of the queue and not updated frequently enough.
