We have 50 employees in 3 offices - and have found it to be a really useful internal communication tool.

Each person has a 'private' G+ (apps) account; we share stuff, have threaded conversations, etc - it's WAY better than email for a variety of things, and all the conversations remain limited to people from our organization.

It's totally not what G+ was intended for, but it works well.

would be interesting if G+ ended up being a Yammer competitor instead of a Facebook competitor.

Do you trust G+ enough for that? It doesn't encrypt your data.
