I have been averaging about 3 per week, but about half of my hubs were prompted by questions, such as yours; I believe the quality and follow-through of the suggested hub guidelines has more impact than the amount of hubs. Follow some groups that are in you areas of interest and you will find natural connections there. Getting buzz is what helps everything.
Most of the good comes from interacting with the hub pages community of talented publishers. "Giving each other a hand up" builds each one of us that much stronger.
