I haven't spun any articles yet but from what I've read so far it is inevitable and I have read where other hubbers have done mild spins to keep their blog posts from going into the archives.
If your writing 2 posts per day I don't see how you cannot do it. My first hub was A post I had put on squidoo for photography. I didn't realize i needed totally fresh content for this article site. I erased it from here but I could have spun it enough to be accepted.
In fact this morning I looked at a free spinner online and what it did was to take an article and give you choices for phrases and nouns. Some of it I liked better than my own writing and some of it was way off.
If you have valuable information to release I don't see what's wrong with changing it up a little to get the word out and save a whole lot of time in the process.
