When a blog article appears in the 'community bulletin', there is no way to know which section the article is posted under. And when you click through to read the blog post, the blog UI doesn't tell you which section it is posted under either.
The Stack Overflow blog is broken up into five sections; each serves a different purpose. I may be interested in posts about what the 'Company' is working on (for example) but may have no interest in their 'Engineering'. Even when I'm reading an article, I don't have that context of what the post is about.
Both the blog post and the announcement should show which section the article is posted under.
