I wrote 3 Hubs in 4 weeks. Every Hub took me about a week. I do research, I read a lot on Hubpages on the topic and then I start to write. I look for pictures on the web and review my Hub many times before publishing.
I'd rather have good quality content instead of high quantity, not feeling satisfied about the content at all.
Receiving insightful comments on every Hub is one of my goals. Something I can not achieve if I write just for the amount of Hubs. I wouldn't do well on the 30 Hubs in 30 Days, because I spend so much time on every Hub.
I'm patient enough to see how things go in the future.
