I have a heap of family and friends who live in a different country to me. I'd love an old school Friendster / early Facebook-style social medium where we could share posts, but the tapping mechanic makes this impractical for me.
Visits are great and all, but they require money and planning with more than one person. And I'm lucky - I can travel. Some folks can't go home - war sucks, poverty sucks, sickness sucks, busy work times suck, etc. If I were still in the US, I might not even get a chunk of time off work.
Travel is probably getting a little less likely considering the current situation with jet fuel as well.
