I agree with others, the homepage _looks_ awesome, but it could use at least a tiny bit more info, links to existing blogs, something. Might just be me, but I didn't assume the get started link would take me to an editor, and I wasn't ready to go through a signup workflow. Might help to make that a little more obvious ("go to the editor").

Editor also looks pleasant. Reminds me quite a bit of Telegraph (https://telegra.ph/)
