It's a splog! It serves no purpose but to duplicate other people's content, sometimes other people's duplicated content, and has no value to anybody but their owner.
There is no such thing as a quick fix. There is no replacement for your brain. There is no software that can magically create coherent 100% unique content for you.
AGC is an autoblog, it pulls contents from websites all around the internet. Such as pulling RSS feed ( I avoid it because I had to link to the original website), my favorite is pulling from amazon, because you can connect your amazon affiliate and autoblog. Of course I do not recommend autoblog because your own content is still the best, but if you run many blogs, you might want to consider it. Autoblog can be useful to provide all useful links to the visitors, IMO.
