Hi Qiaochu! This is Aaron!

Here's something I wrote about it on Facebook:

It was great. My mind was blown 5 or 10 times a day.

I'll write more about this, but until I do here's one example of the type of stuff I learned:

There is a big difference between a) thinking about a list of pros and cons to something, and b) actually writing the list ON PAPER (or a computer screen). (It's also important to keep listing stuff after it stops popping right in your head. There are tricks that help with this.)

Another example: Sometimes people get in arguments with you not because they disagree with something you did but because they are afraid you don't care about them.

I also made a lot of new friends. It was fun!

I'd be interested. My guess is that other LWers would be, too.

I would.
