Today a standard becomes 9 years old. But hardly ever noticed: The Syndication-Module 1.4.1 of RDF Site Summary 1.0.
What is it good for?
Apparently some of you publishing posts less than 10 times per day. Shame on you ... not!
WordPress, however, assumes that you can not even stop, so write it in the RSS feed:
In plain English: Every feed reader should check once an hour, if you finally wrote something again.
Anyone who wants to relieve his server from such a thing, can change that. In the
functions.php you write this two lines:
add_filter( 'rss_update_period', create_function( '', 'return "daily";' ) );
add_filter( 'rss_update_frequency', create_function( '', 'return 4;' ) );
A few feed reader keep it by that but other don't. But even if there is only one: You've saved a few resources that you can use somewhere else.
