These are curate / aggregate sites. The built-in feed reader will work. However, the rss only gives you 15 articles or so. These recipes use screen scraping to pull down a whole bunch -- good if you are new to the sites and want to get some older articles. You can also pick out which categories you want.
Happy thanksgiving
Many thanks to
Kovid and all the contributors.
PS: for some reason, timefmt doesn't seem to do anything.
