Before you actually start your blog, determine what stories you want to share. Ask yourself and/or your co-founders these questions:
Additionally, make sure that your content is well-written in terms of readability and grammar. Failing in these areas will take away from the credibility of your blog.
It's a war of attrition. Blogs are great because they can demonstrate thought-leadership, they can serve as jump-points for other interesting content, they can show your alignment with your customer base, and give that sense of "these guys/girls know what they are talking about".
It will start out with minimal hits, and a lot of frustration, but it will build, especially if you run social campaigns and encourage sharing.
When is the right time ? Right away. There is nothing worse than visiting a blog that has 1 or 2 posts on it, and nothing else. Build a library, you can promote it on an ongoing basis, and the numbers will grow steadily.
