In fact, open source might be critical to your business chat needs.
If you work with sensitive information or need to make sure that all communication stays behind a firewall, self-hosting might be your best option.
And while no tool, not even CC0, can guarantee a complete relinquishment of all copyright and database rights in every jurisdiction, we believe it provides the best and most complete alternative for contributing a work to the public domain given the many complex and diverse copyright and database systems around the world.
Unlike the Public Domain Mark, CC0 should not be used to mark works already free of known copyright and database restrictions and in the public domain throughout the world.
CC0 helps solve this problem by giving creators a way to waive all their copyright and related rights in their works to the fullest extent allowed by law.
CC0 is a universal instrument that is not adapted to the laws of any particular legal jurisdiction, similar to many open source software licenses.
I would advocate that for your team collaboration needs, you pick a tool that's exclusive to work, though not everyone agrees on this.
Personally, I find it too easy to be distracted by non-work conversations when I reuse the chat feature of, say, a social media tool.
There's still a perception out there in some circles that chat applications can be a distraction, and I do believe it's important to have a commitment to reel in off-topic threads before they create a cognitive disruption.You didn't think we'd be able to start this list off without talking a little more about IRC, did you?Internet Relay Chat, or IRC, is a protocol which dates back to the late 1980s.Dedicating works to the public domain is difficult if not impossible for those wanting to contribute their works for public use before applicable copyright or database protection terms expire.Few if any jurisdictions have a process for doing so easily and reliably.And it's equally important to be able to give yourself the space to work uninterrupted when you have tasks that require longer periods of concentration.As I write this, for example, I'm using at least two team collaboration tools, but the notifications are silenced so that I can check in periodically as the breaks in my work allow for it, just as I silence social media notifications when I really need to .What tools work best for you depends a bit on your situation, but might include anything from mailing lists for email communication, Git or Subversion for version control, a wiki or Etherpad for collaborative authoring, a shared task list for organizing workflow, or even a full-fledged project management suite.One collaboration tool which has become indispensable is team chat.I like to keep work separate so I can turn off personal communications when I'm at work, and vice versa. Slack quickly became the darling of software development circles, leading to the displacement of many other tools.An article in The Next Web proclaimed "Slack is quietly, unintentionally killing IRC," and this switch has also come to many open source communities.
