I think the threat's definitely there. Facebook wants to eat everyone's lunch, and they're basically knocking on doors in LinkedIn's neighborhood.

LinkedIn can be described at the 'Facebook for business', it doesn't feel like a stretch that faceboook might someday want to become the facebook for business.

- The overlap is small for now, but the threat is serious.

- The growth is slowing down

- Every product attempts to expand until it has API. Those products which cannot so expand are replaced by ones which can. Linked closed the API.

I wonder if the domain name for this wry old industry observer is for sale : https://en.wikipedia.org/wiki/Fucked_Company

It's still owned by the same guy. http://fuckedcompany.com

We need that site back.

FB for Work looks like a competitor for Yammer i.e. an internal social network for companies offering internal communication with notes, status updates, etc...

LinkedIn is primarily used to professional networking outside your company. Keeping in touch with ex-colleagues, recruiting, sharing industry-specific posts, etc.

Facebook at Work is aimed at internal networking, so communication among large teams, company news / communication, etc.

FBWork is for internal company communication. Does it let you connect to others externally? Does anyone use LinkedIn for internal communications?
