Facebook is the best way to keep in touch with my family at all hours of the day and night, taking into account the different Time Zones. It's not that intrusive, so long as you adjust your Notification settings accordingly. I find it essential, since my brother and sister-in-law and their kids are working and living overseas at the moment. Email is so old, so limited and so out of step. Skype is great, but you can't use it as and when.
Yes, you get all the photos of coffee, dessert, breakfast, lunch, supper, dinner, snacks, etc etc. And the sharing of bizarre videos. And the comments upon comments upon photos. And the adverts. And the "Do you know so-and-so?". But... you also get the general snapshot of your family's life - if they know how to use Facebook properly. My elderly parents hardly ever update their status, my brother hardly ever posts or shares or comments. But my sister-in-law loves to share photos and videos of what they've been doing, which is nice to see.
So, yes to Facebook - long may it live!
