Where can I share my ideas, opinions, articles, research and writings that isn't a blog or social media?

It is the world of social media and its outreach is unparalleled. You can use it as a great way to make people aware of your ideas. Still, it is entirely up to you. Wordpress is also a viable option.
But the best way would be opening your own website. But when you open your own website, you will also have to ensure that it is visible in the search engines and that is going to take one heck of an effort. So all the best.
