Welcome to another installment of This Week in Spring! Since we last spoke I've presented at conferences and to customers in London, Beijing, Shanghai and Singapore - where I am now. Tomorrow, Wednesday, I'll be speaking at the Singapore Spring Meetup - join me! It's been quite a few days!

• I liked my buddy Richard Seroter's review of our SpringOne Platform event a few weeks ago

• Mitsuyuki Shiiba, on the Hatena blog, put together a brief and essential look at Pivotal's Reactor project
