I see italki is sometimes useless.

I have been trying to communicate with people on italki, and while I have found a few people who are very kind and serious although, people mostly are helpfulness. , most people aren't helpful. Sometimes, I feel that these discussions are just funny chats and NOT for exchanging knowledge and the experiences. Being a learner in an IBT program, I am very serious, but there is a lack of seriousness on italki. I considerably believe that any general discussion in English benefits my studying but NOT as I wish. That may be a misunderstanding, and there are some important benefits for me which I can't pick up. Generally, I hope my thoughts are just misunderstanding and there is an opportunity to benefit from using italki.
