An RSS version of Whirlpool’s fantastic daily roundup is hosted at http://fergofrog.com/wproundup/wproundup.rss. For more details (including source) please read the blog post at http://fergofrog.com/index.php/2011/01/whirlpool-daily-roundup-rss-feed/.
NOTE: Please set your reader to not download it too often (every 20-30 minutes is fine), it is hosted on my home internet connection and I can’t handle too many regular requests. This feed is updated hourly so even if your reader is set to download every 20 minutes it’ll only see an updated version every 3 downloads.
