Hi! I just installed this plugin. I like it very much. I have only one issue. I shared a link through the bitly bookmarklet (everything is working good) and the title of the shared page is showing up correctly on the bitly account but the WordPress widget is showing only the shortened link, it happens also on other old bitmarks. I'm using the latest Atahualpa theme for WordPress. Hope this help, let me know for future version. In the meantime I'm setting those showing only the bitmark as private so they don't show up in the widget.
Thanks for this great plugin and the bookmarklet.
