A simple example to show how to use the SyndicationFeed class to load a feed and how to handle the items.

using System;
using System.Linq;
using System.ServiceModel.Syndication;
using System.Xml;

class Program
{
    static void Main(string[] args)
    {
        string feedUrl = "http://feeds.delicious.com/v2/rss/tags/paul.van.brenk";

        SyndicationFeed feed;

        using (XmlTextReader xReader = new XmlTextReader(feedUrl))
        {
            feed = SyndicationFeed.Load(xReader);
        }

        // max is more appropriate
        //var sum = feed.Items.Aggregate(0m, (x, y) => x += Decimal.Parse(y.Summary.Text));

        var max = feed.Items.Max(x => Decimal.Parse(x.Summary.Text));

        // select item title and relative weight for items with a relative weight > 0.1 
        var normItems = from i in feed.Items
                        where (Decimal.Parse(i.Summary.Text) / max) > 0.1m
                        select new { Title = i.Title.Text, Weight = Decimal.Parse(i.Summary.Text) / max };

        foreach (var item in normItems)
        {
            // 15 = highest possible value for consolecoler (Magic Number)
            Console.ForegroundColor = (ConsoleColor)(15 * item.Weight);
            Console.Write("{0} ", item.Title);
        }

        Console.ReadLine();
    }
}
