By happenstance I never started using social media much, and when I stumbled onto the Deep Work mindset I began intentionally avoiding it.
One thing I'd like in my life is an intellectual community, where I can routinely go to find people's thoughts that I'm interested, routinely produce thoughts people are interested in, and engage and be engaged with on those ideas. A few things I've seen recently have slightly updated me that twitter might be useful for this.
I've already seen Zvi and others talk against facebook, but I haven't heard many people talk about twitter.
What has your experience been with using twitter to find, engage with, and share interesting ideas?
I agree with this completely. I would add that the "Lists" feature changed the way that I use Twitter for the better. I now have lists for each of my core interests and & topics -- Economics, Aviation, San Francisco, etc. -- and turn to those when I'm in the mood for specific information relevant to those areas. It helps that all of the tweets are in the context of a specific topic, versus the normal feed, where everything is reverse chronological and jumps from topic to topic.
