How to do RSS right

I love RSS. There are very few sites I visit regularly, but dozens I like to hear from when something new gets posted. Today I subscribed to the Lifehacker feed (something I'm not sure how I neglected until now) and was given the following options:

Perfect. I hate sites that don't include the full post in their RSS feed (hint guys, I'm using RSS because I don't want to visit your site) and this gives me the option of getting the full post and still getting Lifehacker a little scratch from ads, or avoiding ads in my RSS but having to visit the site to get the full info of the stories I'm interested in. Really useful as well to see the "top stories only" option which, on a busy site like Lifehacker, is probably a godsend to many people and also, for the masochistic, a feed with full comments. Other sites could take a hint from Lifehacker and provide people with a choice in how to receive their RSS.
