(P2 is the name of the theme that the WordPress blog you are curently reading is running. The linked article below describes the effect P2 had on their company)
It completely transformed how Automattic works internally and I think is one of the most valuable things we’ve adopted in the past year. I’m on the road a lot, and sometimes my only connection is checking the mobile-optimized P2 on my iPhone.
I’m excited about P2 partly because blogs provide an incredibly robust infrastructure on which to build more advanced apps and this is a good example of that.
