+ Since June 18, 2013 dilbert.com strips are not accessible anymore
+ directly from the RSS feed, this message is displayed instead:
+
+ Dilbert readers - Please visit Dilbert.com to read this feature. Due
+ to changes with our feeds, we are now making this RSS feed a link to
+ Dilbert.com.
+
+ How unhandy is that, was it because of a management decision?
+ Maybe a parody dilbert strip is needed about this issue...
