Of course blogger supports to display feeds directly with the feed page elements. And you can simply generate a clip in Google Reader to put in in your blog. However, you have little control over the style and content. You can do a lot of things using Pipes without programing but as of now it's very slow and unreliable.
This is an example display, you can put it here, at the side bars or almost anywhere.
The 2nd piece of html code should be placed where you want to display the feeds, one for each display with unique ID's:
Without styles, the display will normally blend in with the default styles. Since the feed is appended to the division, you can put something in the division first such as titles.
The parameter n=3 is to limit the number of items to display. There are other parameters in the GData API, but not all are applicable here.
You can customize any of the follow parameters like this:
var block = new WriteFeed('testfeed');
block.title = 128;
block.source = 100;
block.summary = 256;
block.from = "<br/>";
block.unique = false;
block.max = 1000;
block.except = "a source url";
block.front = "your front page";
These parameters are optional. If you don't specify, the default will be used.
title : limits the length of the title, 0 to omit
source : limits the length of the source URL, 0 to omit
summary : limits the length of the summary, 0 to omit
from : the characters or html tags between the title and source
unique : only one title and summary is taken from each source
max : the maximum number of items allowed. If unique=false, max = n by default
except : a source url to include always, even if the number of items is max+1
front : typically set to your front page, so the feed only shows up on your front page, current there's transition effects.
