I have created a Keyboard Maestro script that takes the current Safari Tab and uses Bret Terpstra’s heckyesmarkdown.com service to generate a markdown version of the page (in readability mode) and then paste the Markdown Content of the page.
I have a keyboard combination assigned to it. My workflow is to create a new note in Obsidian, hit the keyboard combination, wait a second or so, then copying and pasting the page title into the Obsidian title field. (This could be automated as well, but I ran out of time 
)
The script – and /today and /tom(orrow) helper scripts – is available on GitHub: https://github.com/yatil/obsidian-helpers/releases/tag/0.1

Hope that helps (It’s my first contribution to this community.)
