How SendGrid Built Its Developer Evangelist Strategy to Reach Critical Mass

Wasn't it a SendGrid developer evangelist who got a programmer fired from his job because he had the bad luck to sit in the row behind her at a Python conference?

She overheard and misunderstood some dumb joke he made about "forking code", took his photo, used Twitter to "out" him for sexism and he got fired.

I don't know what their "evangelist strategy" is, but I always remember that incident when someone suggests SendGrid, it revealed a pretty nasty attitude towards developers, so, I deploy Mandrill instead.
