I use XSLT because I want my website to work for users with JavaScript disabled and I want to present my Atom feed link as an HTML document on a statically hosted site without breaking standards compliance. Hope this helps.
Yeah, but WHY? If they are on the website, why would they want to look at the feed for the website, on the website, in the browser instead of just looking at the website? If the feed is so amazing, why have the website in the first place? Oh yeah, you need something to make the feed off :D
Could you run XSLT as part of your build process, and serve the generated HTML?
