I'm glad there is real data on this. I kept explaining to people that our email and social habits in SV are a complete outlier vs. the rest of the world.
So, before knowing there was reliable data, you constantly made unfounded claims?
You made a good guess. Is that something to brag about? An opinion that you feel the need to "constantly explain to people" borders on ranting... (an embarassing past-time of my own)
Let's say it was strong empiric evidence (e.g. on event invites, I always saw this, SV event invitation emails had the lowest open/clicks vs. other parts of the country) Same email, different regions. Same result. I also get the regular 'I hate emails, I don't click or read them' from a lot of coworkers, despite being the main revenue channel. Yeah, it's fun to be right. I'm bragging about it.
