Feeds vs. Browsers
The stretchtext examples don’t work if you read this weblog in most news readers — especially not if you read them in a river-of-news style reader. They depend on CSS and javascript, and newsreaders won't know about javascript and probably won’t use our styles.
I suspect this is intractable, and that it represents a long-term limit on the utility of newsreaders. News readers are great for headlines and snippets, but they won't completely replace the browser.
