I haven't been paying attention to my referrers as much lately, but I probably should. Because, when I do, I find things like another implementation of BookmarkBlogger in Python, this one by David Edmondson.
His version has many fewer requirements, using only core Python libraries as far as I can see. One of these which I hadn't any idea existed is plistlib, "a tool to generate and parse MacOSX .plist files". When I get another few round tuits, I'll likely tear out all the XPath use in my version and replace it with this. Bummer. And here I thought I was all clever using the XPaths like that in Python :)
