Upsides are all great... If you start, though, stick with it. It becomes a marketing deliverable just as important as anything else, since it is public-facing. If you choose to abandon the project, you just wind down the blog. Just remain consistent about content delivery - if you promise to blog once a month, make sure it gets done. Make the blog easy to find and connected to the rest of your project's public website. Transparency for users has nothing but upside, provided you respect their attention and commitment to your project.
