As Mark Pilgrim and Jon Udell discovered last month, Radio UserLand has a bug in its “News” page (an RSS aggregator), where a perfectly correctly encoded feed that includes sample HTML will interpret the HTML rather than displaying it. It looks like UserLand is in no hurry to fix it, if they plan on fixing it at all. Lucky for me, that’s one advantage of dynamically generating my RSS feeds in PHP, rather than having my tool create static files for me. A little user agent sniffing, and if it’s Radio come a callin’, I just replace every & with an &amp; (and if that displays properly in a browser, a bug-free RSS reader, and in Radio, I’ll know I’ve done it right).
