I am developing an online management platform for certain type of business and I thought that it would be a really good idea to engage possible customers from an early stage by keeping a blog about the product development and the features it supports and getting feedback from potential early adopters as the product goes through the different development phases. And of course, the blog will be hosted on the main product domain (ex: blog.MyProduct.com). Thus, when the product is launched the customers will still visit the same domain name.
I envision the blog to have diagrams of the business model of our business, screen shots of the different interfaces of the online management platform and a place to take suggested features proposed by the customers with (+/- 1) votes on the suggested features. Also, a weekly updates on the development of the product and a place for Q&A for potential customers or early adopters.
So, is it a good idea to start a blog showing all the details of my business, getting feedback from potential customers, showing the product development …etc? Is there an example of such a website?
