Squible is a theme to the extreme as it is a very different blog design based around a group of supported plug-ins. A very interesting theme that you really have to see to understand how different it is. I see many “higher echelon” bloggers going towards this kind of design and set-up.
The purpose of theme (besides putting out something that’s different from the herd) is to promote the use of social networking within WordPress. How? By including the tag system I built that sits on top of WordPress categories into the theme. Other neat features include an advanced layout, support for multiple plugins, the ability for registered users to add tags, livesearch, ajax commenting and an archives page with support for extended live archives.
