Hello, @yunaidy! This is @anggreklestari from the @OCD team. Welcome to Hive Blockchain! absolutely, from Hive you can learn many things every day, and also make new friends.
Well, you can explore the communities that are suitable for your content. You can read about the communities supported by OCD in this post [https://peakd.com/@ocdb/ocd-communities-incubation-program-update-136]

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.

Have a great day!
