What do you use over Google Maps and Facebook?
For Maps, I really don't know of any alternative. And I now make some mapbox-gl applications for the office. There just doesn't seem to be any real alternative.
For Facebook? I can actually almost completely unplug. That said, it is the easiest way to get pictures of the kids to family. I could setup a website, but I can't imagine it would be as easy or as effective. With the emphasis on effective.
