Spinning still works, but you cant just spin on the word level anymore, Google is far too good at seeing synonyms. Plus you shouldn't just scrape some ezine article that's been spun a thousand times already. To give you an idea of the level of spinning that im doing now, this is what im doing for my 2.0's.
10 - 12 paragraphs
3 - 5 sentances in each paragraph
6-10 grammatical rewrites of each sentence
hand spin all synonmims that make sence.
spin each set of sentence rewrites into one bracket, spin all possible permutations of the sentence order in the paragraph, then select between 7 and 10 paragraphs in a random order for the articles.
Then images and video etc etc...
The uniqueness of these HUGE spin tax docs is immense, even to the human eye. Expertpeon is the one you want to talk to about spinning he really knows his stuff.
