For the last 3 years I've been compiling some of the best content databases that you can find on the web - for my own projects - and I'm releasing them for sale on ScrapingWeb.com.

Lots of good stuff, if you are going to build a rich content sites / applications.

These are not quick solutions / sites that are doomed to decline in SEO, like ready made website scripts with databases used by hundreds of other sites. These are just data, originally and freshly compiled and re-structured that you can develop into content-rich (both in terms of volume and structure) websites with your own unique information structure and custom web designs.
