How are sites drumming up publicity for their site blogs?
Some of our users, I suspect, don't even know the site has a blog. We could use system messages when we put up a new post, but that's clunky - you can't schedule those in advance - and, if there's a new system message every week for something non-critical, then the system message will lose it's urgency. And the messages are meat for more urgent events in any case.
