“Yammer”
We had it at my last company.
The problem was the only ones that used it was people with nothing useful to say.
Also, being international it had too broad a reach to be useful.
For a family it might be good but we don’t own the domain (I don’t think, I have to check with my brothers). Also getting my family on the same page on anything (see what I did there?) was a minor miracle. LOL!
You’re welcome!
I’ve used Yammer before in a corporation. My experience was similar to yours as most of the posts were of little value.
For a small group or family, I can see it being much more useful, especially if you are trying to avoid Facebook and all the junk that accompanies it (spam, facebook games, surveys, etc.)
The trick is (1) owning your own domain and (2) getting your family to use it. At the company engagement with the platform was low and a lot of people don’t want an extra login when all their “friends” are on Facebook.
