A small but 'real' post. Twitter stores all dates in a well, nonstandard way, so i came up with the following extension for my project to handle this:

    public static class Extensions
    {
        public static DateTime ParseTwitterTime(this string date)
        {
            const string format = "ddd, dd MMM yyyy HH:mm:ss zzzz";
            return  DateTime.ParseExact(date, format, CultureInfo.InvariantCulture);
        }
    }

What i does is takes the string from the XML response formatted like this "Wed, 08 Apr 2009 19:22:10 +0000" and parses it as an DateTime. Having it as an extension allows me to use in inside LINQ queries. (And I needed something to test the SyntaxHighlighter script) Updated 2010-09-06: Twitter changed it's format in the api
