I have just started both, but I keep to I guess sort of a plan, I write one article for each, also add in one article for ezine articles and one squidoo page then start over. Sometimes only get one article for each a week, 3 blogs, sometimes less, but it seems to be working. I am getting some traffic, minimal. I think that you just have to have some type of plan. This worls well for me, because of my schedule.
