While there are other Services to merge Multiple feeds into One but Yahoo pipes is the service that we would be using.The reason Behind is that Yahoo pipes is far more flexible and you can add your Custom Rules per feed.

3.Similarly fetch the Feeds of all the Blogs that you wish to show In your list.For example if you wish to fetch the Feeds of 4 Blogs then create separate feed windows for each feed.Do not Merge them into One as We will be adding Rules to each feed later on.
4.Now you need to Add rules to each Feed.this Depends on your taste and What you wish to Show on your Blog or RSS reader.
Let Us Suppose you wish to show 1 post from each Blog in an Ascending order in your List.To achieve this :
5.Add the function “Truncate” from the Left pane for each feed.The Truncate function is Used to Limit the Number of feeds Of each feed Item In the resulting List.Pipe each Feed with the Truncate function and Set the value that You wish to show per feed.

7. Merge the outputs of all the Truncated Feeds with the Input to “Union”.
8.Next Pipe the Output of the “Union” function to the Input of “Output”.That’s It.The Hard part is Over.
