@kgfuglsbjerg So I think that Micro.blog nails the flow aspect of writing to your site. Inputing your thoughts is the reason I do it so regularly and don't like missing a day.
However, and this is where things break down, you need to offer a simple way for people to customise their site. This shouldn't include any coding really. It should be a series of dropdown menus. Change the colours. Change the typography (typeface and size). Maybe add an image/header (if you want). And if it was awesome there should be at least 5 variants on this (1 column, 2 column, photoblog, etc).
