The editor only lets you write plain text, select from a few fonts, and use Markdown for formatting. It's difficult to use Write.as for more complicated blogging or creating a full website.
Con The writing space is very limited
The writing window is limited to only about one-fifth of the page, the rest is just blank. You can only see about three lines of text at a time. Seems like a mismanaging of space.
