Blog posts are an easy way to gauge interest in your problem area and potential solutions. Write up a post around the user need and the solution that you have in mind and share it on social media networks and through paid channels. Use readership data, commentary and responses to better understand interest in the area and to get feedback about your proposed solution.
Blog posts are best used when the venture team has something concrete that they are exploring. Though they are useful at the problem validation stage they can be particularly helpful when a team is considering ideas for solutions.
Blog posts can be quick and easy. If conducted as part of an on going strategy they can also be used to recruit interested users for future testing or feedback.
