As a short preface - I was very positively surprised by the quality of the sessions. I will most definitely join more (virtual) EA conferences in the future.
Here are just a few things I take away from the conference:
Founding an EA aligned start-up has been on my mind for a while now but it was all very vague and I was not sure, if I would a good fit for that particular branch of altruism.
Steve Thompson's talk "How and Why You Should Start a High-Impact Nonprofit" was inspiring in that regard. He made the point that it is is generally hard to know your fit before trying it. Charity Entrepreneurship's application process, however, is quite good at judging the fit and the program provides feedback on applications.
Long story short - I took the time to apply last night and am looking forward to hearing from them. Have a look at their website and their short quiz to find out if it could be something for you too.
Shakeel's Session "How to Write Well" gave me some additional ideas on how to get better at (surprise) writing. If I had to quote one (very basic) thing it would be "Don't use a long word, when you could use a short one"
I'd recommend watching the session as VOD.
