Enterprise social network for news sharing

We use Honey. There are definitely a bunch of competing/similar products. We found honey to be just right for what we need, a private repo for article sharing internally. Specific features we need/must have 1. groups, 2. Tagging 3. chrome app
This is similar to Inc (http://sendtoinc.com) that Tom posted a while back here - http://www.producthunt.co/posts/238. I've played with Honey and while I like the design, I haven't found a use for it personally.
Yeah, I'm in the same boat. I don't really have a use case but it might be cool for a team like Makeshift.
