I'm still trying to process all the things that happened to me while working at Twitter - the last month before I was forced to resign was just something I don't think I've ever seen in my career of 20+ years in the network/security business.

But what made Twitter great? What do I miss most? Our former core values were key ingredients:

* Grow our business in a way that makes us proud.
* Recognize that passion and personality matter.
* Communicate fearlessly to build trust.
* Defend and respect the user’s voice.
* Reach every person on the planet.
* Innovate through experimentation.
* Seek diverse perspectives.
* Be rigorous. Get it right.
* Simplify.
* Ship it.

Yes. These were our values for years. And it was destroyed in a month.
