It would be difficult to start an article about blogging without talking about the KING. WordPress has been around since 2003 (or 2001) and now powers almost 40% of the whole world wide web. It started as a blogging platform, but it's now much more than that; you can build nearly any website you want with it.
There are two versions of WordPress: the self-hosted one at WordPress.org, and the hosted one at WordPress.com. And since we're talking about no-code tools here, I'll suggest you try the second one. Just create an account, choose a theme, mess around, and start writing!
