A couple of you have pointed out that my site's feed has—for some time now—been stripping all excess line-breaks out of my entries. After one more gentle nudge today (thanks John!) I decided to do some digging. And sure enough, it was a quick and extremely easy fix. My Atom feed (it's not a public feed, it's the one that Feedburner grabs to generate the public feed) had a couple of key fields with
convert_breaks=“0” (I ask you, what the hell kinda default value is that, Six Apart?) So, to my dear feed subscribers: all should be better now, and I apologize for any inconvenience.
