Phoo and Bloo are:

• Object-oriented
• Massively flexible when it comes to the front-end interface, database interface, etc
• Fully separated, code-wise, between the front-end interface (web) and the back-end (currently MySql)
• Built of components, called "SnapOns" and "Overlays". In Bloo, everything you see is a SnapOn or an Overlay
• Secure from the start
• Full of the prime features of mature blog software (posting, comments, trackback, rss, spam-control and many more).

Phoo represents the general base classes upon which Bloo, the Blog-specific class codeset, is built.
