It's not that hard. Most of MBTI is stereotype.
Gmail: The ENTJ
On the main Gmail page there is this description:
Well, the intuitive is an easy give-away. N!Gmail is built on the idea that email can be more intuitive, efficient, and useful. And maybe even fun.
Efficient and useful? Maybe fun? Sounds like T!
Gmail coordinates with google calendar and sends you text messages all the time. Did somebody say E!?
All those labels? Organizing tools? Surely J!
I'm so distracting myself from real work.
