Can you talk to native speakers?
I used to use Livemocha.
That site allowed native speakers to listen to my recorded sentences and grade them. It was useful to hear many different actual Italian speakers repeat my sentences back to me so I could hear what I did wrong.
If you found someone to be specifically helpful, you were able to make friends with them and find them on Facebook. I made some great friends that way!
Is there anything like that here?
I loved LiveMocha. It's too bad it got all messed up when it got bought out by Rosetta Stone.
Duolingo doesn't have anything like that. although I've seen a couple of folks use Vocaroo and post recordings, asking for comment. I made a little step-by-step guide to using Vocaroo as a result (https://www.duolingo.com/comment/16226812).
It hasn't caught on much, possibly because the way the forums are set up there doesn't tend to be a good mix and exchange between native speakers and learners like you see on sites like Lang-8 and the old LiveMocha. I agree, it would be quite beneficial.
