The 30/30 is not an "official" challenge unless you count making an online announcement as "official" . If you already are writing one Hub per day, you may not need to do the 30/30. Since I did have some experience doing writing online projects before coming to HubPages, the 30/30 was helpful for me because the 30/30 deadline is similar to completing online deadlines. Only you are the one who sets the goal and completes it. The 30/30 builds confidence for writers who have never tried writing for an online company, and even if you've already had the online writing experience and got paid for it, you will get to know yourself even better as a writer. This is what I came away with when I completed my two. I found that I could write my 30 long before the deadline, then keep writing a Hub a day or more after that. Others may see this process differently, but if you don't complete the 30/30 for whatever reason, you can always go back and do it again. Personally, I don't care about my Hubscore. My score drifts from 89 to 93. I write to please me--not the Google gods.
