Hi there -- I'm trying to improve my Chinese, which has been at an intermediate level (B2?) for a long time. I've been inspired by the Polyglot Gathering in Berlin, and I'd like to raise my Chinese to a more advanced level. I want to understand more about the mistakes I'm making. I know people can understand me -- but it's important that I learn to speak and write correctly. I am an American, and I am part of the internet and startup community. I'd be happy to talk with people about startups, and share my experiences there!
