Some more questions/suggestions:
- Front page says it's free, no mention of the pricing plans that only show after you login.
- I'd suggest mentioning all the features you support in the main page. ie there is no mention of custom domains.
- Some basic usage metrics would be nice.
- A way to export/import content would be nice.
ps. I created a project with www as the slug (www.sidepage.co) and since chrome is hiding the www it's even worse. Please feel free to delete the project and restrict the use of the www slug.
