1) have horrible navigation 2) lack a good editing experience / CMS, especially when working with a lot of images & videos. Markdown is actually distracting in this case because I have to break my workflow to upload these assets to my CDN. 3) are not designed to meet the needs of product marketing - they can’t have analytics added or they can’t be branded to match the rest of the marketing website.
Maybe I just haven’t found the right tool yet.
