So really impressed by the Personas feature in Firefox.
Would it be an idea to have Personas for WordPress themes?
So (logged in) visitors could choose their own persona.
One could design a theme, and all that would change would be the image in the header and/ or the color scheme. Or possibly the header images of widgets as well.
This could be a plugin, or maybe at some time in the future be a part of core. So have a standard WordPress theme which comes with WordPress, and then Personify your blog for yourself and your visitors. Or for example it could be part of a theme framework such as Thematic.
What do you think?
