I've used Interpals for over seven years and I can pretty much tell you this website used to be a good website to chat, talk and creat lifelong friendships and maybe meet a girlfriend, believe it or not.
Back in 2011, I met tons of people who I still talk to, few of them should I say, and back then it was nice and it seemed that people genuinely wanted to talk to you, get to know you and even learn your language, but here's when things kind of changed, from 2014 on I couldn't meet a single person, things got bored and it didn't have the sparkle anymore, you just would scroll up and down all day long and not a single soul would get back to you, which was very annoying, by the way.
All in all, it's worth trying and good to do some language exchance, but nothing more than that now, although you might be the lucky one and go past "hi, how are you?"
