There is a problem that I have with Google Reader that I find to be particulary annoying. There are some RSS feeds that when I add, all the item of those feeds have their update time set to the time I added them. I am fairly sure this is not due to the RSS itself, because it provides an update time and creation time that is different from what is displayed.
Example (no bug) : http://stackoverflow.com/feeds/tag/node.js

Am I doing anything wrong or it's just a Google Reader bug ?
