If they don’t tell what they’re doing, nobody knows. This includes prospect customers, target investors, potential hires, etc. SEO could be a reason but more often than not blog posts are not optimized and/or are on a different domains. It’s also good as education material, for example if you build dev tools or sdk or sw for other devs, certainly you’ll have docs, but I think having blog post with concrete use cases helps a ton. IMO blog posts are an indispensable tool for customer acquisition.
