While working on my latest project, this board proved very useful, because it allowed me to post a bunch before creating a project page -- something I'd rather not do too early, for various reasons. And it was popular! People read it, and even answered. Once I did have a project page, that allowed me to post a couple of more involved devlogs, and in turn link to them from here. So in my opinion the board complements the project devlogs. But yes, it can be abused, and how to fix that is a good question.
