I have it and have used it only sparingly.
It's good if you need to write content and need some ideas. It pulls pieces of content from a bunch of different sources, so you can easily find pieces of content with just a few clicks.
You do have to weed out some crap content sometimes, which can be a pain.
It is a nice tool if you are just pumping out content sites though.
It's also not bad if you don't mind pushing the envelope a little and going a little black hat.
Using it white hat means you use it to help you research and organize, and then you go back and do some editing.
If you don't want to edit shit, you can just take a sentence here and a sentence there and use it as is. It's unlikely taking one sentence from 10 different sources will get you into hot water.
Some may not be okay with it, but others say, "it ain't cheatin' if you don't get caught". LOL
I don't know if I'd drop $67 bucks on it though.
Take a look around on Google and see if you can find it cheaper.
I got it for alot less than $67 if I remember correctly. I'm pretty sure I only paid $27 or $37. So look into that.
I fucking got off topic alittle.....beer......but basically my advice is that it's a good tool if you are in the Adsense game and trying to build content sites by hand. It can save you serious time and writers block frustration.
but before you spend 67 see if you can find it cheaper.
