Pebble is a huge productivity drain. Lots of people use it to discuss anything other than work-related topics. Corporate, regional and district management use it as a cheerleading or "worship the almighty Eddie" platform.
Its original intention to be used as a collaboration platform fell by the wayside long ago. Now it's a Facebook for Sears workers. I don't know if there would be any other company that would allow workers to shoot the breeze so excessively on company time and on a company platform. Yet there are tons of active, non-work related groups for just about every topic you could think of.
I've tried to use it to get my work-related questions answered (#ithelp mainly) but I never get any of my questions answered or issues resolved, so I no longer use it. I won't miss it if it goes away.
Pebble and all of these other technological "innovations" like the iPads or "Call Sears" on the SNCs are totally unnecessary and a waste of money. Pull the plug on it all and get back to the basics.
