Online stuff:
I have several friends in the DC area who I met because I made this post.
I found my job because I applied to a CFAR workshop, and that led me to attend the Effective Altruism Summit instead (funny story there), which is where I first met the team I work with.
Phil and Eliezer have critiqued my fiction, and I've done the same for Phil and Vaniver.
Meatspace stuff:
I met about a dozen good friends in Boston through LW meetups and lived with several of them before I moved to SF.
These days, my primary social group is maybe 50% self-identified rationalists and 100% people who are serious about existential risk and laugh at jokes about fundamental epistemology.
I'd like to ask everyone: Have LessWrong.com and related online rationalist/transhumanist/Singularitarian communities connected you to people for purposes beyond discussion?
Bonus points if an online contact led to an important connection. We already know that face-to-face meetups are a great way to meet people, so I'm curious about connections triggered by online interaction.
I have seen scattered mentions that each of the above has happened, but not enough to get a strong impression of what's going on.
Please answer in comments below. By doing so, you'll be providing social proof that LW and the like can accomplish these things, and so encourage more to happen, increasing happiness in the world.
I added one myself to start.
