 Working on the [http://cavemonkey50.com/code/tumblefeed/ Tumblefeed]
 plugin, I recently ran into a problem. I should first take a step back and
 explain what Tumblefeed is doing.

 The Tumblefeed plugin is designed to create a better feed for WordPress
 tumblelogs. Instead of bombarding readers with feed updates throughout the
 day, the plugin prevents the posts for the day from appearing in the feed
 until midnight. At midnight they're all posted as one item.

 Certain feed readers (namely Feedburner) are not updating the feed due to
 the <pubDate> value not changing. The <pubDate> value is linked to
 get_lastpostmodified. Since the Tumblefeed plugin is not really modifying
 any posts (thus changing the get_lastpostmodified value), the date stays
 the same even though the feed has been updated.

 To solve the problem, I feel a filter hook should be added to
 get_lastpostmodified. The filter would allow me alter the value without
 making any drastic and unneeded database changes.

 As [http://photomatt.net/2007/08/13/tumble-hybrid/ mentioned by Matt
 himself], WordPress tumblelogs are starting to take off and would
 certainly benefit from this change. Right now I have logged around 75
 downloads of the Tumblefeed plugin, so there is demand for this type of

 While I understand under normal conditions a plugin should have no reason
 to filter this value, this is an exception I feel is worthwhile adding a
 filter for.
