Hi everyone, I'm relatively new to italki. Haven't been able to use it much yet due to being very busy. I plan to use skype soon for language exchange however, I have a few questions.

1. Do most people tend to use voice or video chat? I think I would prefer video as I have someone to focus on when I'm talking and hand gestures and facial expression can help when trying to understand/explain. However, I understand that people may not want to show themselves, especially without knowing the other person.

2. Have you found it more beneficial to arrange a topic beforehand or just chat generally and spontaneously. For instance, if having a meeting once a week.

3. What is the most effective way you have found to arrange a language exchange? I see a lot of people prefer 50/50 although not sure if this means each person speaks their target language for the whole session or switch languages half way through the session.

Thanks in advance!
