If spun articles are based on original content, but merely with synonyms or alternate phrases inserted at various points, why would that qualify as original content? Or, would it be original content? What's your thoughts.
Because it has high percentage of uniqueness as article spinning tool is able to provide good no. of synonyms... only one disadvantage of spun content is that it is not readable.
I think that people are confusing different types of spinning. Auto-spinning (even using the latest and best hyped-up tools) produces substandard and often unintelligible content. On the other hand when content is spun either fully manually or semi-manually (software assisted plus human readability check) it can be of high quality. Uniqueness can also be increased by spinning at several levels (i) paragraph, (ii) sentence, (iii) word/phrase, and then (iv) using different numbers of paragraphs, (v) in different sequences. Yes, it takes time and effort but it's worth it.
