why would anyone need this service? I believe the original question was RSS feeds from the site owner being indexed? RSS feeds should be submitted too google webmaster tools to be index by google and Bing offers a similar service too webmasters, After initial submission the webmaster never has to submit again?
If I wanted to push my content using RSS feeds then I would use Ping.fm to push my content and links to third party sites and social media.......
I am at a loss why a webmaster would use the linkilecious site?
