You can keep writing blogs, but if you want to collaborate you should use the actual mechanisms set up by the project to do so. It's fine if you want to blog about this stuff, and it's often a means for developers to get their name out there and promote their opinions and ideas. There is nothing wrong with doing this, but if you actually have an issue with a project it's much faster, simpler, and, dare I say it, polite, to use the actual channels created for exactly this purpose.
