Clarification: Packt is still heavily into Open Source.

I'm changing MY focus. Packt as a publisher remains absolutely committed to Open Source. We've got plenty of new Open Source titles on the way, we're running our usual Open Source CMS award, and have more Open Source titles than ever planned in the next 12 months.
But for the time being, I am exploring other areas and invite book ideas and authors interested in writing on non Open Source topics. Get in touch.
Open Source, I'll miss you.
