I thought it was totally worth it. I spent a lot of time to make sure my hubs were still high quality. I had many ideas of what to write about in advance, so some were already started. My traffic and revenue went up that month and has remained up, although the traffic isn't consistently high as it was on some of those days back in March. Plus, now I have a lot more hubs circulating out there. It was fun to do it with another group of people who committed to the challenge. I wrote a hub about 30 hubs in 30 days, as many hubbers have. You might read some of those to help you get more perspectives on it. Good luck!
