I would create a blog. Download and install wordpress blogging script.
Wordpress blogging script is what powers most of the blogs on the internet. Wordpress blogging script is easy to install, update, install wordpress themes etc.
With a standard websites you'd have to create new web pages using html but with wordpress you just create new pages and publish new blog posts just like posting a new question or answer on this website through a text box.
Wordpress is also good for SEO search engine optimization. And there's a plugin you should install called yoast which will help boost your seo rankings.
