#obsidian's live preview of Markdown is good enough that I actually use it. No other markdown-enabled system has been able to make that claim. I've always written in pure markdown mode and used #Marked to view the rendered version. I still love Marked for all the places that aren't obsidian. (thank you @ttscoff for Marked!) but it's nice to have my main personal knowledge base be good enough at live preview to make my notes look good without outside help.
