For me - to learn and to educate. I have a lot more to learn than I have to educate but i do both. I try to read a lot about technical and economic aspects/impacts of bitcoin so as to better understand how blockchain works and how it can transform other areas of our world.
Bitcointalk has been a mostly wonderful community be a part of. There are some people who abuse their access or privilege but for the most part, people are good. And if you're willing to listen and read there is an incredible amount of really smart people to talk to here.
What's your aim, Thzo?
