I am easy to please when it comes to small and simple things that make my life as a developer easier. For example, I came accross something I had not noticed before in ASP.NET while reading a post from Dave Burke. The HtmlHead class exposed by the Page class as Page.Header. I love this. It makes it so easy to get to, and manipulate the header attributes for a page. A simple act of changing the page's title, style, etc before was a pain. Now it's just setting a few properties.
