Simple writing interface and simple execution.
I still have some questions but this looks like it might be a bit of a winner. I can install it on my own domain pretty simply or just pay for them to host it. I can edit it from any browser. It's simple enough that it just works and I don't have to manage it too much and the theme is good enough to get going. There seems to be a tie in for substack type stuff but I am not interested in that. I do wonder how they will cope in the long term so I think the export is probably an interesting thing.
So Images don't really work as a link from flickr. No preview. Need to be pro to use their photo sharing app. Hmm What will that mean for export?
It does support tags though so #mushrooms would be good but it's not an autocomplete thing. Maybe this editor is just to blank?
