As a CodeGear employee I’m not going to participate in the contest but I thought it would be cool to create a Live Template for making it easier to add XML Documentation comments into your code. Just type in "xdoc" and when you hit enter the template should expand to:
Using "summary" element in the xml doc comment enables Help Insight functionality to display the contents of your comment in the tooltip window when you move a mouse over a symbol in the code editor. The "xdoc" template is very simple and can be downloaded from code central. To install it, select File->New->Other and then in the dialog select Other Files->Code Template. Replace the default template content with the template code and save.

For convinience below is the "xdoc" template, so you can just copy and paste it from here.
<?xml version="1.0" encoding="utf-8" ?>
<codetemplate xmlns="http://schemas.borland.com/Delphi/2005/codetemplates" version="1.0.0">
<template name="xdoc" invoke="auto">
<description>Help Insight XML Documentation comment with "summary" element</description>
<hint>XML Documentation comment goes here</hint>
<code language="Delphi" delimiter="|">
In order to increase the readability of your comments you may want to use "c" tags inside the "summary" tag. Help Insight will use a different font for these parts of documentation comments that are enclosed with "c" tags. This is useful for identifiers. If you want to see which documentation tags are recognized by Help Insight consult "HelpInsight.xsl" stylesheet located in "ObjRepos" directory.
