> no audio / video There are products that are far better for audio and video communication than Slack. At my company, we use Zoom. > no history Can be done with a bouncer if you need it. > no rich features like links, pictures, upload docs ect Is there a reason why an external service can't be used? I can't upload a image here on Hacker News, but I can always include a link to it. > easy bot integration with APIs So I have to use the HTTP protocol to manage a bot rather than checking for certain key words in the message itself. > no archiving channels on the go, Slack is very useful when you have an incident and you create a temp channel and then archive it when the incident is closed. That depends on the settings. One thing that happens every so often at work is that people get trapped as the last remaining person in a channel because only an administrator can archive a channel. In IRC, that's not an issue.
