I recently discovered NaTakallam: http://natakallam.com/
It's a startup that matches Arabic language students with native speakers living as refugees in Lebanon, most of whom are of Syrian origin. The project aims to help provide work opportunities for jobless Syrian refugees. Arabic language students who are keen to learn the colloquial Levantine dialect would definitely appreciate having the opportunity to learn from native speakers, besides making new friends from a totally different background from their own.
