It is very difficult to find the right fit. A language partner who has a similar level, similar goals, similar interests and with whom you just feel comfortable with. Time zones add to the difficulty. Also, many people like to write but feel too shy to talk. While I'm not shy, it's very difficult for me to set up Skype sessions due to my busy work schedule and the fact that I have three kids. So, I only offer video sessions, when I'm 100% sure that I want to speak to that person. In general, I also prefer to write or exchange voice or video messages. It's easier to organise. And about the profile: unfortunately, most people don't read the profile.
