Blogging, oh how I hate the word.
Sharing information with others and talking about things of interest.
I do not think there are many people who want to author a blog. However there are millions of people who like to share, discuss, argue, and ponder via social media.
It's all creativity. Long-form content, biye-sized content, videos, interviews, podcast, drawings, music, memes, poetry. Basically anything that comes to mind.
