Just a way better interface on it. Searchable history, multiple rooms inside rooms effectively. File sharing, lots of niceties that are probably possible in IRC but would take a lot of work. It has changed the way our team communicates, for me I am the only remote guy on a team of 6ish devs. I can pick and choose my hours, work when other guys are off, and still see all the comms that happened while I wasn&#x27;t at my machine.
