I'm pretty sure that ELL could be a very useful site for those who are learning English. However, for speaking and listening skills it wouldn't offer anythings.
As far as we have weekly writing chat, which users choose a subject and have free discussion about it. This is good IMO. However I should improve my speaking and listening skills. I searched on-line Skype users through Google and some other sites to have a free discussion with whom. Unfortunately there's no user spending some time for such a free discussion.
My suggestion would be let's have a weekly free discussion through Skype. Willing users may want to leave their username and other users call them.
I'd be glad to know your thoughts.
