Hello, 
It would also be awesome if you could do an introduction post, so our community can get to know you better. For information on how to write an intro post, please check out the SELF INTRODUCTION section of the post 3 things Newbies should do in their first week on Hive.
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 already found Splinterlands, and you might be interested in the Hive Gaming Community 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.
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.
Since you're new, you may run into an RC (Resource Credits) error when trying to comment/post because you don't yet have enough Hive in your account yet. For assistance with a temporary delegation to get you started, be sure to check out the Gift Giver site.
For now,
