It's a familiar interface if you use FacebookCons:
I did not like that I had to bifurcate to use this tool. I get why, but not all teams are enterprise teams.
I have one team that is very tethered to email and at first blush Workplace from FB seemed like a good way to ease them into real collaboration with a familiar interface. I would still recommend it, but would have liked the option to interface with workplace from my existing account.RJ Lewis Digital has used this product for one month.
