Although I have accounts at other social media, I never ever posted anything. Only when discovering Steemit, I started to share information. For some reason I like it, but like you, I like the simple chat channels more, since those allows much more interaction than this blogging think. The good thing of blogging channels is that posts and comments are more structured and will be easier to search back when needed than chat channels, anything in the history of a chat, generally is lost for later use.
