Hello 
Speaking of community, we have many different ones here on the blockchain, devoted to all kinds of interests. Here's a link so you can check them all out - Hive Communities. I see you're already well acquainted with the awesome Scholar and Scribe community, and I think you'll find these interesting as well -
Also, as Hive can sometimes be quite confusing, the newly launched Newbies Guide should be helpful to you, as it is a growing repository of useful and easy to understand posts about how the Hive ecosystem works. For instance, there's a post in the collection called 3 things Newbies should do in their first week on Hive that you might find helpful.
Please be aware that Hive is a bit different from other social media platforms since you are monetizing your blog, so it is important not to include content that you don't own without sources (and it shouldn't exceed 50% of the post). For more information, check this post - Why and How People Abuse and Plagiarise by hivewatchers.
I'm sure
