The StackExchange team added a new feature today on their Q&A sites like StackOverflow called chat with an expert.
This chat box support is a smart artificial intelligence and can “guess” the answers to your questions because she is after all an expert
Try it out and Enjoy the chat with her
You need to create an account with them to see the “chat with an expert” floating black box on pretty much every page on the site.
