I find Joplin https://joplinapp.org does a good job of producing markdown from web pages and already has sync capability built in. Looks like it would be ideal for working with Obsidian
Exported my Joplin markdown and opened it up in Obsidian. Works like a dream and the best part is Jopli already has it's own web clipper. Seems like a superb match
Thank you, Anand. Despite being 8 years old, Aaron's html2text.py worked perfectly to convert the HN homepage to Markdown. His memory (and code) continues to be a blessing!
