As TUAW is a blog about Apple, I found the following quite interesting:
"As an Apple employee, you definitely get the feeling that blogging about the company is frowned upon. It goes to the extent that, if you have a personal blog about an unrelated topic, you don't even want to mention that you work for Apple."
There are very few company blogs, even with notable exceptions such as Surfin' Safari, their WebKit blog. Still, this is in contrast to Microsoft, where there are numerous blogs by product divisions and personnel. Then again, it's been a long time since Microsoft routinely surprised and delighted their customers and fans, so perhaps Apple is on to something.
