Successful software developer, long standing web development speaker, writer evangelist and expert, John Allsopp has spent the last 15 years working with and developing for the web. As the head developer of the leading cross-platform CSS development tool Style Master, and developer and publisher of renowned training courses and learning resources on CSS and standards based development, John is widely recognized as a leader in these fields. As a presenter and educator, John speaks frequently at conferences around Australia and the world. His idiosyncratic blog Dog or Higher covers a broad range of subjects, particularly in technology and innovation, and is widely read and referenced. He is also a co-founder of the Web Directions conference series. John's true claim to fame, and source of some embarrassment is (semi-publicly) coining the term "Web 2.0" some months before O'Reilly. John apologizes unreservedly for helping to inflict this term on the world. When not bathed in the glow of various computer screens, John is a volunteer surf lifesaver at Sydney's famous Bondi Beach, where he lives with his wife and young daughter, who are the light of his life.
