Here are some wireframes exploring ideas for new frontpages for TiddlySpace.

Simple Frontpage

Pretty much stolen from colmbritton, this design is pretty minimal:

• Screenshots from interesting spaces
• Ability to sign up for the service
• Some testimonials from existing users
• Plumbing, like a "terms and conditions" link

Busy Frontpage

The ideas I was trying to explore here include:

• focussing on the layout and proposition. As a wireframe it looks quite noisy, but I think that the information density is comparable with other sites. I'd point to sites like GitHub that have a similar information density but make effective use of graphic design to keep the visual noise and clutter under control
• striking a balance between explaining TiddlySpace by showing it in action, and an actual step-by-step introduction to scroll through
• maintaining the front page as an ordinary TiddlyWiki so that it can both dogfood the user experience proposition (learning TiddlyWiki by reading a TiddlyWiki document teaching you how to use TiddlyWiki) and can be implemented with existing macros
• having a conventional, spare and spacious front page above the scroll line, with an invitation to scroll down to explore more information
