Hi all... I was wondering if you could help me out with your suggestion on the following: I am looking for free (at the moment) alternatives to a Facebook-like service. The idea is that some of us at work would like to have a space where we can connect our work-related research. Ideally, our workplace should be providing an intranet, but the IT Dept. is a bit short-sighted and have only worked out a solution for themselves. They say that they are testing the platform, but that has been going on for a while. We did consider Google+ but being a part of some private circles, I did not find it interesting and/ or engaging. So, I would like to know if there are any alternatives - free at the moment (hopefully with full functionality). If over a trial period of say 3-6 months we find that it suits our purposes, then we could also opt for a paid service. The only condition is that whatever the solution be, it has to be platform-agnostic (since we will use all OSs across a variety of devices to access the service). Thanks in advance.
