On: Barriers faced by newcomers to open source project...

[theflagbug]

For projects hosted on Github, take a look at https://gitter.im

I'm a maintainer of a reasonably big open source project and it works great for us, since you can link issues/PRs directly and get a Github activity log right next to the chat.

It also preserves the chat history, which was one of the big reasons to switch over from IRC.
