I would agree that it's not "solved", but I do think that there are many non-paid solutions that will satisfy the majority of small to medium businesses. Slack-likes seemed to be pretty popular for awhile, and most are feature competitive as far as the internal communication aspect that Work at Facebook, sans the video chat. I'm a little torn on this as the product itself does seem like a natural use for Facebook's platform, and I'm mildly surprised they didn't do this soon. On the same note, that they didn't do this sooner makes it feel a bit more "me too", and I'm not confident the adoption rate will be strong enough to justify it going forward. Since the UI is just a mildly tweaked version of vanilla Facebook, I wonder if they had internal numbers showing that people were already doing this to justify the commitment, or if they're just hoping it will stick. I honestly feel the Facebook UI is just way too cramped and smooshed for being all that productive with, but I am also not an avid facebook user, so my opinion may be worthless. (I think VK's layout is a lot cleaner, for example...) Right now I'm not convinced Facebook is offering enough to convince any existing users to migrate. I'm not sure it offers anything enticing over other Slack-likes to really convince users to pick it over other services. Though I appreciate them separating the two types of accounts, I think this just raises the barrier of entry, which was already pretty high compared to others.
