I just checked and I’ve had 3 hits for my blog’s RSS feed from a legit-looking browser user agent string this year. Almost literally no one reads my site via RSS in the browser. Quite a few people fetch the feed from separate clients.

I wouldn’t spend 5 minutes making that feed look pretty for browser users because no one will ever see it. I don’t know who these mythical visitors are who 1) know what RSS is and 2) want to look at it in Chrome or Safari or Firefox.
