Hello, @dannt! Welcome to Hive Blockchain! Indeed, like you said, this platform is perfect to share idea, in different communities.
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!
