Think of the tin rss feed as the feed you create with the black hole script.

Then when it is on an actual page with some other content, it becomes a feed for your silver sites.

Or you can point the rss feed from your silver sites to the same blog that the black hole script is feeding.

The idea is to use the black hole script to start creating content for a blog or website. It is nearly instant compared to many other methods and very scalable.

It gives you some momentum to get going and when you look back after a month or two, you will start to see blogs that are indexed, ranking for keywords and might even have some PR.
