Flow is worked on full-time by Facebook’s developer infrastructure team. They’re often around and available for questions.
The flowtype tag on Stack Overflow is a great place to ask questions and find answers.
To report a bug, please create a GitHub issue. This is also a good place to ask questions, but it’s harder to find answers once an issue has been closed.
Many developers and users idle on Freenode.net’s IRC network in the #flowtype channel.
@flowtype and #flowtype on Twitter are used to keep up with the latest Flow news.
