And Horwitz wrote on Facebook:

Some quick personal news: After four years at Twitter, I’m moving on. I can’t say enough good things about the extraordinary people I had the good fortune of working with while there. I’m leaving proud of what we accomplished and will take with me amazing memories and more importantly, friendships.

And I’m super excited about where I’m headed next. I’m doing product communications for … this product. I’m joining Facebook this month. Woohoo! I’m really grateful for this opportunity (thanks [vice president of technology communications] Caryn Marooney!). I can’t wait to get to work!
