I guess that on this site there are many people who are very busy with work and family, but they also study languages and want to have a language partner. On the other hand, circumstances can change very often and they need to cancel a language exchange meeting, which can be unpleasant for a language partner. <o:p></o:p>
What is your opinion about the problem?<o:p></o:p>
People ask for exchange then disappears.
Probably, many partners prefer text chat only and avoid real conversations.
It's so hard to find a serious partner here.
A Teacher (professional or community tutor) is better for me.
