In an ideal world everyone would have full-content RSS feeds. Until then making your own isn’t that hard — and it’s getting easier by the day with mash-up tools like Yahoo Pipes. Here are some I’ve created:

• Digg Direct – links directly to the stories, instead of wasting your time with Digg’s comments page (Python source).
• BBC’s 10 Things We Didn’t Know Last Week – they have their own feed, but it isn’t full-text. This one is (‘source’).
• Archie Comic of the Day (Python source)
• The Joy of Tech Comic – they have an RSS feed, but it doesn’t have images (Python source).

Update: added links to source code.
