Hi Wouter,

Vincent's solution is the most correct one from the Java development and 
best practice point of view. But for some less experienced developers it 
might be a bit difficult imho. So I can think of a way to work around 
this (i.e. do a quick dirty fix).
An easier solution, though not the most elegant one, would be to write a 
piece of Javascript code to be executed on page load. It should search 
fpr links in the RSS block(s) and write the "rel" or "target" attribute 
to "_blank". The only problem is that you should include that script via 
xwiki.jsx.use(...)  on each page you want this feature on.

The Javascript could look something like this:

document.observe("xwiki:dom:loaded") {
   var rssLinks = $$('.rssitemtitle a'); //the css selector for links in the 
'div's generated by the {{rss}} macro.
     link.writeAttribute('target', '_blank');

I hope it helps. Cheers!
