I've been meaning to ask. Do you know if there's any Maghrebi Arabic talk radio to be heard on the web... not counting Maltese? I'm not sure how much Maghrebi there is in the media at all, come to think of it.

Talk radio?

Not as such. There are shows that use dialect rather than MSA.

Here's a useful current list of online stations:

You'll see Radio Tunis, which has some talk shows, and Medi 1, which also have some talk shows in dialect (as well as French and Arabic news) - but it is largely a music station. The other two Moroccan stations don't work.

The Algerian stations I have never bothered to listen to, I am not even certain they work.

Thanks. Lots of chitchat on the Algerian stations. In fact, that's much more than you have out there for any other dialect.

The relentless Maghrebi-French(-MSA) switching is very amusing. It seems hardly anyone can go for a whole sentence without a pinch of French. Do people do that in Morocco?

Well, perhaps I should give the Algerians a listen.

Re the switching, among well educated people, absolutely. Tunisia, Morocco and Algeria all share that. Functionally with near perfect bi or tri lingualism, it's just easier.

I do it all the time in speaking with Maghrebis in my sector. Indeed, in convos w people in capital markets, I'll have a melange of dialect, French and English.
