The latest “AdSense Facts & Fiction” from the Google AdSense Blog states an issue about many of adsense publishers turned-mass web site developers:
Fiction: Publishers can put ads on auto-generated pages or other copied content that was not created by them. Fact: We don’t allow sites with auto-generated or otherwise unoriginal content to participate in the AdSense program. This is to ensure that our users are benefiting from a unique online experience and that our advertisers are partnering with useful and relevant sites.As you read the rest of the post it’s not clear if this applies to sites that republish syndicated content. In additions:
Sometimes we come across sites that are using software to generate automated content. These sites might look like normal news sites, but the information is completely plagiarized. Scraping content and passing it off as one’s own is not only wrong, but it also happens to be a serious violation of our policies There’s a good amount of content that can be copied and republished per the author’s guidelines. So it seems that this directive if mostly pointed to splogs, such as the many “blogs” that copy content from Domain Name Wire and republish it in its entirety.The post also said that sites should build "long term" users. Which means adsense encourage publishers to run forum or community sites. However, those kind of sites are kind of hard to manage. If you ask me which system would I use, I would suggest Drupal. However, Drupal is same as Google which means developer friendly. Millions of normal users feel that is hard to use since to first step to use it is hard. It is because majority of users are not familiar with Linux based system. From now on, I will publish a few tutorials for everyone about how to deploy and activate a drupal7 web site!
