Hey Cathy, thanks for sharing about WordAi. It certainly is interesting, to say the least. I guess at some point all of us would want to automate our business and will look into programs like these for a solution. The example you showed gave me a very clear indication that the algorithm isn’t quite there yet. You seem too lenient in grading it because to me, it is practically unreadable. I believe hiring writers is a better use of that money.
I've ranked websites in the past with spun content, and now they are still on #1 position of google. First year (2014) google found me because my spun was really bad, many paragraphs were just copied and my position drop from #2 to around #20 after a panda update. Later I cleaned all my text with better spun (I didn't buy any article!), my ranking went up again, and with more backlinks I reached #1 and it is still there
