I'm pretty sure most SEO experts already regularly read blogs of search engines, i.e: Google Blog, MSN Blog or Yahoo's Blog. They often give you nice updates from inside the company.
Not spectacular things but for example, in late january, Google made a post about how you can defend against blog spammers by using an element in your link tags.
If you're not reading them already and you're interested in SEO, I'd suggest you look into them every once in a while:
Google Blog
MSN Search's Blog
Yahoo! Search Blog
