Hello, @sir.blc! Welcome to Hive Blockchain!
you're right. As you said, you can express anything freely here, with many community choices according to your interests. you can take part in the music competition on Vibes Community; share your drawing on Sketchbook Community.

Then, you can explore more communities that are suitable for your content and supported by OCD HERE

For tips and information as a Hive newbie, click here: newbie guide.

The important thing is Hive is a bit different from other social media platforms since you are monetizing your blog. You can't include content that you don't own without sources. For more information, check this post: Why and How People Abuse and Plagiarise.

If you have questions or concerns, you can hop into OCD's Discord server and we'll gladly answer your questions.

I'm @anggreklestari from the @OCD team.
Have a great day!
