I'm having the same kind of problem for a while now, and I wanted to share with you all.
I've been trying really hard to find japanese language partners, but every single time this is what happens:
1) I make a polite and friendly contact saying I wish to be their language partner
2) If there's something on their profile that is of our mutual interest, I talk about that
3) They reply back saying that they will be happy to be my partner.
4) I reply back, thanking for the kind return, and make a language related question
5) They never reply back.
Every.
Single.
Time.
Should I do something different? What do you think?
Thanks :)
