Feature request: friend-request-by-mail: Pay Friendster $1 to send a postcard with a unique QR code. I've seen something similar for user/address verification on a local community website (but it's free to send the postcard).
I shouldn't require international travel - over an ocean - to talk to my siblings on the internet on a social app.
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.
