I wanted to start a new blog but not with my own content. I would like to use some service such that my blog gets automatically updated with the similar post as posted on someone else blog. I exactly don't know what that service is and how to use it but I have seen a blog with similar structure. You can check that blog at http://www.bloghendra.com/. This is exactly what I am asking for. You can see it doesn't have any of its own content but content is published on its blog from other blogs automatically. I think either technorati, feeds or ping services plays an important role in this. If someone know about this please let me know.
