My last day at Yahoo will be 2010-01-22.

I’ve gotten an offer from Proofpoint which is too good to ignore. The opportunity to drive the direction of a product at an early stage, including having a lot of input about the choice of technology and team, is very exciting. Also, though this was not the primary factor, the position is significantly more financially rewarding than I believe that the next few years would be if I stayed at Yahoo.

Yahoo has been a mostly great company to work for, and YUI is by far the best team that I’ve worked on here. It’s a shame that I didn’t join YUI sooner; I still feel like I just got here. The quality of this team made the decision very difficult, and that says a lot about the job that Eric Miraglia and Thomas Sha have done building it.

If you ever get a chance to work at Yahoo, take it.

I feel so very fortunate to have met so many of Silicon Valley’s bright minds in the last 4 years, and to have learned so much about the web, about business, about people, and about the science and art of software development. I’ve been a student, a teacher, an expert, an amateur, a mentor, and a mentee.

Thank you all so much for what you’ve given me.
