The ART of conversation applies even with italki chatting. Finding mutually interesting topics and being able to stimulate conversation is a skill you need to learn. What good is getting someone to give you a topic for conversation if you are clueless about it? You have a world of things to talk about with others. Food, clothing, Gossip Girls, boys etc. Just jump in!

There are a lot of topics that you can discuss. But at the beginning, maybe talking about our own background and learning experience might be interesting. You can also share some interesting experience you have had for learning English with your partner. I sometimes, also asks my friend about their study and work. I saw in your profile that you are working on accounting now. And maybe you can also discuss something related with accounting?
