added feed to pubsub

Need now to see if it works :-).

I have set it up for the keyword jazar. Let's see if it works ...

Next step is to see what we can do with it - I guess that they are only "techys" using this service at the moment - but you can expect soon people looking for a specific item and using this tool to find out where they can buy it.

this may become a very profitable channel for SEOs!
