言語交換相手を探すのに必要な機能は？ (What kind of functions on italki will be necessary to find langeuage partners?)

最近、この「ディスカッション」で言語交換相手を募集する方が増えているように思います。私は、その理由はitalkiの言語交換相手を探すシステムではうまく相手を探せないからではないかと思っていますが、みなさんは言語交換相手を探すためにitalkiにどんな機能が必要だと思いますか？

I'm afraid that number of people who look for language exchange partners here (on this "Discussions" board) is increasing. I don't intend to criticise them at all. I suppose the reason might be that the system, that is, a kind of search engine, on italki can't help them enough to find language exchange partners. What kind of functions on italki do you think will be necessary to find language partners?

Sorry for my typo in the English title!
