I remember back in the day, when nobody knew of other chat client other than mIRC. It was a beautiful time to be a part of the web, as most of the discussions and revelations happened exactly on mIRC. Scrollback is taking IRC to the public, and instead of competing with it – it allows to integrate your own IRC channel within it’s platform.
It’s a lovely project, and I wish the team all of the best. I’d use it on my blog, but I’m not into live chat thingies and frankly it would just bother me most of the time.
