I have a website that includes a blog. The issue is that posting on the blog is only possible from a computer, and the experience is poor when attempting to do so from a mobile device. Since creating a mobile app is not feasible, wouldn't it be wonderful to have an API that enables users to develop their own applications for publishing posts on their websites?
