Re: Slack
When that crap gets introduced to an organization by a pointy-haired-boss, productivity drops
You nailed it.
We had since forever a local Jabber server for intra-communication. No voices, no pictures, no distractions.
Then we hired an outsider to "revitalize" our flagship product. Oh Lord. First thing he did was to tear down Jabber and slap us Slack on our faces, just because "notifications from successful builds and new commits". Which we already had in e-mail.
And then many other things went downhill. The ship he was supposed to save is sinking faster, but in an angle where captain's quarters will be the last to get under the ocean.
AC for obvious reasons, as I haven't (yet) left the ship
