Of course, it doesn't replace the conversations here on Lingq, as you wouldn't get any reports and probably no (or almost no) corrections, but I think it maybe could be a way to enhance your speaking ability. Maybe it could even be possible, that more users will take a conversation here on Lingq, as they will get to know each other (at least for me it's much easier if I already know my interlocutor) and they already have taken the first - and most difficult - barrier to start speaking for the first time.
It could also be possible, that some users of Paltalk get to know Lingq and will be future members. But if you don't like the idea of a public room, we could also open a private one, only for Lingq users.
By the way, I've already opened a test room called "Language Exchange Café" to see if it works (I've never opened a room on Paltalk before ;-)).
