My small business (<20 employees) is looking for an internal social network platform to replace Yammer.

Yammer recently binned its inline PDF commenting system, which we used a lot to group proof documents and content before publishing and releasing.

We also used it for general socialising and information sharing, within our teams and with the office at large.

We've looked at Slack and HipChat amongst others, but from what I can tell, none of them offer an easy way to share files and collaboratively inline comment on PDFs (and ideally other files like images).

So: team social network platform suggestions please. Ideally is:

  • file commenting capable (very important, not found one with this)
  • online / in cloud
  • available on mobile & desktop
  • configurable group chats
  • personal messaging
