blog.stackoverflow.com was certainly a good idea. However, this has had the side effect that a lot of content is added at a faster rate. Much of that content is very broadly dealing with "company news" like new staff, related projects, the API, the progress of Area 51, Kittehs, and such.
While that is perfectly suitable for the company's official weblog and makes for fine reading, for an occasional user solely interested in changes to how the site works, it has become extremely difficult to keep track of blog posts related to those. The post about the new bounty system is already preceded by five other posts has been pushed to page 2. In the "old" blog, it would stay on the front page much, much longer, and the ratio of "technical" posts to announcements felt about equal.
Maybe starting a "maintenance blog" or "status blog" that deals with outages and changes to the system would be a good idea. The way it is now, I find it difficult to tell users popping up on Meta reporting "bugs" in the bounty system to please read the blog.
