So since Slack has been so successful for our community , far more that IRC has been in terms of participation and useful discussions (at least the 2 years I have been around) it made me wonder if I could find an open source alternative to Slack that is at least as good as it if not better without a very different workflow (so we have to learn everything from zero) all the big pros and something that could easily interface with Pharo. Ladies and gentlemen meet Rocket Chat https://rocket.chat/ The good news about Rocket chat is that it seems to have all the pros of Slack like close integration with tweeter, github etc etc . It has clients for all OS and mobile devices. But not the big cons like the 10.000 messages limit ( which we have long exceeded). Its open source and most importantly written in javascript and we know that pharo can interface with javascript in many diffirent ways . Hosted on Github and deployable with open source technologies. And even its license is MIT. The reviews I have read about it are very positive. So what do you think ?
