Going to http://feedproxy.google.com/ILoveTypography in my browser or curl, gets the last 15 articles, the number is set by the blog engine I'm guessing. Adding the feed to Google Reader however, I can scroll down to the bottom and it'l AJAX load the next 15 or 20 items in the list, and you can keep scrolling down and it'l forever load up more articles. It's not just feedproxy.google.com - I tried with the MSDN blog as well, as a newly subscribed feed.
Is Google keeping the full feed? Do I have to manually scroll through the full blog history in Google Reader, save the AJAX generated HTML then parse it to get the info I want?
