The idea is that RSS readers should analyse the update frequency of a feed and automatically adjust their polling frequency, instead of polling every five minutes and generating unnecessary network traffic. Hmmm… I don’t really think that would work, given that the process of blogging is not something that has a defined predictability. For example, there are blogs that have not been updated for two months – does that mean I should only check them every other month, thus missing a new post by four weeks in the worst case?
Here’s something that *might* work: weblogs might specify a “please don’t poll faster than x minutes” tag in the feed, allowing readers to react to it. Additionally, the blog server could add statistics of the last updates to the feed, allowing readers to adapt *so they wish*.
What do you think?
