"Add this to my Radio wish list: I'd like a way to indicate what categories have been added to a post. This would be an effective way of showing how I think a post should be categorized, and would also reinforce the notion that there are other ways to browse this site. The more I think about it, the more I think that Jenny's right on when it comes to meta-data: we need to figure out how to add useful meta-data to weblogs. "

I concur. I render category labels on my web site but they don't become part of the post included in the database or the rss feed.

A kind soul volunteered a cleaner version of the following macro for my Item template.

<%
local (adrblog = radio.weblog.init ());
local (adrposts = @adrblog^.posts);
local (postNum = "<%paddedItemNum%>" ) ;
local (adrpost = @adrposts^.[postNum]) ;
if (! defined (adrpost^.categories)) {
   return "";
};
local (adrcats = adrpost^.categories);
local (buf = "");
for adr in @adrcats {
   local (name = nameOf(adr^));
   local (adrcat= @adrblog^.categories.[name]);
   local (link = name);
   if (defined (adrcat) && defined (adrcat^.htmlUrl)) {
      if (adrcat^.htmlUrl != "") {
         link = "<a href=\"" + adrcat^.htmlUrl + "">" + name + "</a>";
      };
   };
   buf = buf + " " + link;
};

buf = "<small>" + buf + "</small>";
return  buf ;
%>

You can see examples of it on Blue Sky Radio.
