Ray Blakney here with Live Lingua (more about me here). I've enjoyed your site but wanted to pass along a resource that your readers should find interesting -- our guide to Argentinian slang terms.
It's more thorough than the article you link to, and I'm hoping you'll swap out the link for ours:

Thanks for your time, I really do appreciate it and I think your readers will as well.
